Analytical Study Designs: Case-Control and Cohort
- Previous year questions on Analytical Study Designs: Case-Control and Cohort for NEET PG (National Eligibility cum Entrance Test - Postgraduate), from the Community Medicine section of the exam.
- Most questions here come from previous-year papers of Indian postgraduate medical entrance and licensing exams; where a paper and year are recorded the question carries them. The image-based questions are original vignettes written around an openly licensed figure, and were never asked in any exam.
- 120 live questions in Analytical Study Designs: Case-Control and Cohort.
- 4 of 120 questions carry a verified exam year: 2017, 2018.
- Community Medicine is worth about 25 of 300 questions on the exam. See every subject’s weightage.
- Question set last updated 3 Sept 2026.
