Study by subject

Public health

Public health rests on precise definitions, indicators and study designs that are easy to confuse. Lumi quizzes you on this vocabulary until the difference between two close ideas is clear.

How to turn this subject into cards

Make one note per concept, such as incidence, prevalence, bias, study designs or screening, with its definition, formula and an example. Always quiz yourself in pairs, for instance incidence against prevalence. The trap is reading a case and applying the wrong formula because the words look alike. Lumi helps you retain definitions, formulas and criteria.
