What does the 'P' stand for in a PICO question?
Show answer and explanation
Correct answer: B. Population/Patient/Problem
PICO stands for: P = Population/Patient/Problem, I = Intervention, C = Comparison/Control, O = Outcome. This framework is used in evidence-based dentistry to formulate searchable clinical questions. 'Placebo' is part of 'C' (comparison). 'Prevalence' and 'Prognosis' are study design terms, not parts of PICO.
