Abstract

Objective The purpose of the study was to assess whether there were sex differences in stroke severity, infarct characteristics, symptoms, or the symptoms-deficit relationship at the time of acute stroke presentation.Methods In a prospective study of 505 patients with first-ever ischemic stroke (the Ischemic Stroke Genetics Study), stroke subtype was centrally adjudicated and infarcts were characterized by imaging. Deficits were assessed by National Institutes of Health Stroke Scale (NIHSS) and stroke symptoms were assessed using a structured interview. Kappa statistics were generated to assess agreement between the NIHSS and the structured interview, and a Chi square test was used to assess agreement between the NIHSS and the structured interview by sex.Results In all, 276 patients (55%) were men and 229 (45%) were women. Ages ranged from 19 to 94 years (median, 65 years). The mean (+/-SD) NIHSS score of 3.8 (+/-4.5) for men and 4.3 (+/-5.2) for women was similar (P = .15). No sex difference was observed for the symptoms of numbness, visual deficits, or language. Weakness occurred in a greater proportion of women (69%) than men (59%) (P = .03). Stroke subtype did not differ significantly between sexes (P = .79). Infarct size and location were similar for each sex. The association between symptoms and neurologic deficits did not differ by sex.Conclusions We found no sex difference in stroke severity, stroke subtype, or infarct size and location in patients with incident ischemic stroke. A greater proportion of women presented with weakness; however, similar proportions of men and women presented with other traditional stroke symptoms.

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.
