In incidence based mortality studies, the pooled mortality reduction was 25%(RR,0.75; 95% CI, 0.69-0.81) among women invited to screening and 38% (RR, 0.62; 95% CI, 0.56-0.69) among those attending screening. The corresponding pooled estimates from case control studies were 31% (OR, 0.69; 95% CI, 0.57-0.83), and 48% (OR,0.52; 95% CI,0.42-0.65) after adjustment for self-selection. As shown by Duffy et al, when widely different estimates of absolute benefit are standardized to a common RR, number of screening rounds, and duration of follow-up, and then applied to a standard population and baseline risk (specifically, in this example, the UK Independent Review scenario described above), to estimate the NNS, a nearly 20-fold difference (from 111 to 2000) found in 4 well-known estimates of the NNS/NNI(number needed to screen/ number need to invite) to prevent 1 breast cancer death was reduced to a range of 96 to 257women screened to prevent 1 breast cancer death.
