A 24.4% quit rate for iCanQuit would yield a 20% higher impact compared to the 20.4% quit rate for QuitGuide; for every 25 adults who smoke, iCanQuit would result in one additional successful quitter compared to QuitGuide (number needed to treat = 25).
“Furthermore, a 24.4% quit rate for iCanQuit would yield a 20% higher impact compared to the 20.4% quit rate for QuitGuide. For every 25 adults who smoke, iCanQuit would result in one additional successful quitter compared to QuitGuide (number needed to treat = 25) [84].”

The Background states that a 4-percentage-point increase in smoking abstinence corresponds to a number needed to treat of 25. It does not report the iCanQuit or QuitGuide quit rates or their claimed 20% relative difference, so it supports the NNT calculation but not the study-specific figures. (LLM, conf=0.88)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
