“Although the relation between folate status and depression has been addressed since the 1960s (99), studies that include measurements of tHcy as well as folate and vitamin B-12 started in the 1990s (100,101).”

“However, other observational studies confirmed the association (36,37,44), and intervention studies have now demonstrated that coffee raises tHcy levels (45,46), an effect that is probably mediated by chlorogenic acid (47) and caffeine (48), which are coffee constituents.”

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.
