Fig. 5 Standardized Z scores were calculated using nutritional group (Milk, Soy, Control) means and standard deviations (SD). The GH, free testosterone and IGF-1 response (area under the curve) of individuals with Z scores greater than +1 (i.e., ‘responders’) was compared to the response of individuals with Z scores less than −1 (i.e., ‘non-responders’). A ‘trainability’ statistic was created by summating the Z scores of each training adaptation measure and responders (Z sum > 3) were compared to non-responders (Z sum < −3). There were no differences between responders and non-responders; n = 8–10 for each group

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.
