Age at onset (A), initial National Institutes of Health Stroke Scale scores (B), and discharge modified Rankin Scale scores (C) of 33,178 patients with acute intracerebral hemorrhage and 125,722 patients with acute ischemic stroke from a multicenter registry between 2000 and 2018: The Japan Stroke Data Bank. Edited based on the data from Ref [2]. The National Institutes of Health Stroke Scale (NIHSS), a serial measure of neurological deficit, is a 42-point scale that quantifies neurological deficits in 11 categories, with a score of 0 indicating normal function without neurological deficit and higher scores indicating a greater severity of deficit. The modified Rankin scale grades the degree of disability or dependence in daily activities using scores ranging from 0 (no symptoms) to 6 (death). In Panel (B), the boxes represent the interquartile ranges, the lines across the boxes indicate the median values, and the whiskers represent the 10th percentile and 90th percentile values
