Figure 1. Association of Percentage Infarct Volume With Admission NIHSS Score, Its Subitems, or Regional Infarct Probabilities: Female vs Male.

Figure 1

(A) Admission NIHSS score and its subitems (weakness and ataxia). (B) Regional infarct probabilities in cortex, striatocapsular region (corona radiata, basal ganglia, and internal capsule), and cerebellum. Mixed-effects quantile regression analyses were performed to investigate the sex differences with adjustment for age, prestroke modified Rankin Scale score, hypertension, diabetes, hyperlipidemia, atrial fibrillation, smoking, a history of prior stroke, percentage white matter hyperintensity volume, and onset to MR imaging time. Dots and error bars (red for female patients and blue for male patients) indicate the adjusted mean values and their 95% CIs, respectively. Green bars show the distribution of percentage infarct volumes in this study cohort. *p < 0.05 for the adjusted difference between female patients and male patients. Please note that “p for interaction” does not reflect sex difference in infarct expansion–related increase of the values within individual patients. NIHSS = NIH Stroke Scale.
