During a busy Saturday afternoon clinic session in Subang Jaya, your clinic assistant informs you that Ms Tan Li Wen, a 35-year-old staff nurse, sustained a needlestick injury while disposing of a hollow-bore needle after venepuncture. The injury involved a superficial puncture wound to her left index finger.
Immediate first aid was performed with thorough washing of the area using soap and running water. The source patient consented to blood testing for blood-borne viruses; however, as it is a weekend, the results will only be available in three days.
Ms Tan is otherwise well. Temperature 36.7°C, blood pressure 118/72 mmHg, pulse 74 beats per minute and regular. She has no chronic medical conditions.
You commenced HIV post-exposure prophylaxis with tenofovir disoproxil fumarate 300 mg plus emtricitabine 200 mg once daily, and dolutegravir 50 mg once daily.
Her immunisation record shows she completed a 3-dose hepatitis B vaccination series 17 years ago and was documented at that time to have an adequate immune response. You inadvertently requested measurement of circulating antibody levels against the hepatitis B surface antibody*, and the result returned the next day as 7 mIU/mL (laboratory reference for protective immunity ≥10 mIU/mL).
Correction: The previously stated “antigen” has been corrected to “antibody” for accuracy.

Mr Adrian Lee, a 43-year-old marketing consultant in Kuala Lumpur, returns for follow-up after treatment for syphilis 12 months ago. At that time, he had presented with a painless genital ulcer. Blood testing demonstrated reactive treponemal-specific antibody tests and a quantitative non-treponemal titre of 1:16. He was treated with a single intramuscular dose of long-acting benzathine penicillin and received counselling regarding partner notification and safer sex. He had a documented negative sexually transmitted infection screen 6 months prior to that episode.

A multicentre randomised controlled trial, the Heart Outcomes Prevention Evaluation Study (HOPE), evaluated the effect of ramipril on cardiovascular outcomes in high-risk patients aged ≥55 years without heart failure. A total of 9,297 participants were randomised to receive ramipril 10 mg daily (n=4,645) or placebo (n=4,652) and were followed for a mean duration of 5 years. Baseline characteristics including hypertension, diabetes mellitus and smoking status were comparable between groups. The primary composite outcome was myocardial infarction, stroke, or cardiovascular death. During follow-up, the primary outcome occurred in 651 patients (14.0%) in the ramipril group and 826 patients (17.8%) in the placebo group (relative risk 0.78; 95% CI 0.70–0.86; p<0.001). The relative risk reduction was reported as 22%. The hazard ratio adjusted for covariates was 0.78. Subgroup analysis showed consistent benefit across diabetics and non-diabetics. There was no statistically significant difference in overall adverse event–related discontinuation.
Based on the results above, how many patients would need to take ramipril for 5 years in order to prevent one additional patient from experiencing the combined outcome of heart attack, stroke, or cardiovascular death?
Ms Nur Afiqah Rahman, a 23-year-old physiotherapy student in Kuala Lumpur, presents with gradually progressive difficulty hearing over the past 6–8 months. She first noticed difficulty following conversations in small group discussions and has recently needed to increase the volume on her phone.

A bedside assessment using a vibrating tuning fork placed at the midline of her forehead produces a sound heard equally in both ears. When the vibrating fork is placed on the mastoid process and then moved adjacent to the ear canal, she reports that the sound is louder when the fork remains in contact with the bone on both sides. An audiology test was done and audiogram showed as below:

A 53-year-old woman attends for follow-up after participating in routine biennial screening. She is asymptomatic, has no significant family history of breast cancer, and her mammogram report states “no evidence of malignancy.” She asks how reassured she should feel, noting that she has read online that screening tests are not perfect and may “miss cancers.” You review population screening performance data derived from large mammography screening studies, including program data aligned with international evidence such as the Swedish Two-County Trial.
A published summary for asymptomatic women aged 50–69 years reports the following approximate estimates in a screening setting: sensitivity 87%, specificity 94%, cancer prevalence 8 per 1,000 women screened, recall rate 4%, and false negative rate 13%. The report also presents likelihood ratios and predictive values calculated for this population prevalence.
Mary’s specific concern is: “Now that my result is normal, what is the chance that I actually don’t have breast cancer?”
Which parameter from the report most directly addresses her question?

Several recent randomised controlled trials have evaluated the cardiovascular safety of selective COX-2 inhibitors in patients with osteoarthritis and rheumatoid arthritis. Individual trials reported varying estimates of myocardial infarction and stroke risk, with some lacking sufficient power to detect uncommon adverse vascular events. A group of researchers systematically searched MEDLINE, EMBASE and Cochrane databases, predefined inclusion criteria, assessed methodological quality of eligible trials, and extracted outcome data independently by two reviewers. They then statistically pooled relative risks using a random-effects model to generate a single summary estimate of major vascular events associated with COX-2 inhibitor use compared with placebo or non-selective NSAIDs. Heterogeneity was assessed using the I² statistic, and publication bias was explored with a funnel plot. The authors concluded that COX-2 inhibitors were associated with an increased risk of vascular complications overall.
Which of the following best describes the study design used by the researchers?

A prospective diagnostic accuracy study evaluated the performance of prostate-specific antigen (PSA) testing for detecting prostate cancer in asymptomatic men aged 55–69 years. One of the large European trials, the European Randomized Study of Screening for Prostate Cancer (ERSPC), reported outcomes from a screened cohort compared with usual care. In a diagnostic substudy of 1,000 men who underwent PSA testing followed by biopsy as the reference standard, 200 men were found to have prostate cancer on biopsy. Using a PSA cut-off of 4.0 ng/mL, 160 of the 200 men with cancer had a positive PSA result, while 240 of the 800 men without cancer also had a positive PSA result. The remaining participants had negative PSA results. The investigators reported moderate sensitivity and limited specificity at this threshold. Positive and negative predictive values varied according to cancer prevalence.

Arjun Menon, a 19-year-old biomedical sciences undergraduate in Kuala Lumpur, attends your clinic accompanied by his mother, Kavitha, requesting completion of a medical certificate for his upcoming university examinations. Kavitha reports that Arjun has not attended lectures for the past 5 weeks and rarely leaves his bedroom.
When seen alone, Arjun explains that he believes unknown individuals have been following him for several weeks. He states that during his last bus journey, they released “invisible spores” that have now burrowed under his skin and are monitoring him. He says he has been soaking his hands in methylated spirits daily to “draw the spores out.” He appears restless and intermittently scans the room. He is reluctant to engage in a full physical examination but allows observation. You note erythematous, excoriated lesions over both hands with areas of weeping consistent with chemical dermatitis.

During a continuing medical education session in Kuala Lumpur, a pharmaceutical representative presents data on a newly marketed oral medication intended for primary prevention of cardiovascular disease in high-risk patients. She describes a prospective cohort study involving 2,000 participants with similar baseline cardiovascular risk profiles. According to the presented data, 1,000 patients received the new medication and 1,000 patients received standard care. Over a 5-year follow-up period, 150 patients in the treatment group experienced a cardiovascular event (15%), compared to 250 patients in the control group (25%). The representative highlights that the medication “reduces cardiovascular disease by 40%” and emphasises this figure repeatedly when discussing the study findings. She does not provide any further explanation of how this percentage was derived.
You quickly calculate that the absolute difference in event rates between groups is 10%.
What statistical measure is the representative MOST likely referring to when describing a “40% reduction”?
