Figure 4.

Dyspnea score distribution at baseline, 48 hours, 30 days, and 6 months postthrombectomy. Dyspnea was assessed at baseline and at follow-up visits at 48 hours, 30 days, and 6 months postthrombectomy using the modified Medical Research Council assessment tool (higher score = worse dyspnea). The proportion of patients with each score (0-4) is presented, showing a significant change in score distribution (P < .0001 for available paired assessments; McNemar-Bowker’s test). Mean ± SD and median (IQR) values for each timepoint are shown in the table below the graph (P < .0001 for available paired assessments; Wilcoxon signed-rank test). The sample sizes below each posttreatment timepoint represent the number of patients who had paired measurements with baseline values.
