In the citing paper
“The most common clinical presentation of estrogen-related thrombosis is venous thromboembolism (VTE) of the deep veins of the legs or pulmonary vessels, usually within the first few months of use.”

In the citing paper
“In an international case-control study across 21 centers, the World Health Organization reported in 1995 that increased risk of VTE was apparent within 4 months of starting CHCs, was unaffected by the duration of current type of CHC use, and returned to baseline within 3 months of discontinuing CHCs [100].”

In the citing paper
“In patients with thrombosis provoked by hormonal contraception, the risk is believed to return to baseline levels within one to three months of cessation of hormonal use [100, 107].”

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.
