What messages the terms number need to treat (NNT) and number need to harm (NNH) give to the clinician?

Selim KILIÇ.




Abstract

NNT and NNH terms are epidemiological measures that are commonly used day by day. These terms give their messages to the clinician independent from statistical significance and provide important support when he or she plans patient’s treatment protocol. The aim of this review is to give some clues to the clinicians in order to interpret these two terms.

Key words: number need to treat (NNT), number need to harm (NNH)
