Figure 2. Serial National Institutes of Health Stroke Scale (NIHSS) Scores.

Figure 2.

Box-and-whisker plots show the distribution of NIHSS scores at the time of the index stroke, at poststroke baseline, and during recrudescence in patients with ischemic stroke and hemorrhagic stroke. There were no significant differences between NIHSS scores in the ischemic and hemorrhagic groups at the time of stroke onset (mean [SD], 10.0 [5.6] vs 12.9 [9.1]; P = .19), poststroke baseline (mean [SD], 2.7 [4.1] vs 3.4 [5.1]; P = .63), or recrudescence (mean [SD], 5.1 [4.7] vs 5.6 [5.3]; P = .75). There were no significant differences between groups in the degree of NIHSS score worsening (mean [SD], 2.4 [2.0] vs 2.3 [0.9]; P = .81) or the duration of recrudescence episodes (mean [SD], 18.5 [20.7] vs 16.6 [15.5] hours; P = .81). Boxes indicate the lower (25th) and upper (75th) quartiles; horizontal lines in the boxes, median values; whiskers, minimum and maximum values; and open circles beyond the whiskers, outliers.
