Recently, “number needed to treat” (NNT) has been increasingly reported as an index of treatment efficacy. Sinclair et al. proposed the idea and formula of threshold NNT [
1] (NNTT) below which we can assume that NNT of the medical intervention is acceptable. In order to retain virtue of NNT, which enables us with ease to compare burden with benefit of treatment intuitively, we here show a simpler way to estimate NNTT.
