Table 1.
Demographic and clinical characteristics of stroke patients included in the study before and after propensity score (PS) matching (based on age, sex, pre-stroke mRS, type of stroke onset, time to treatment, admission NIHSS, occlusion site, and pre-stroke anticoagulation). Categorical variable are reported as counts (percentage), continuous and ordinal variables as median (IQR). p values are calculated using chi-square (for categorical variables) and Mann-Whitney (for continuous and ordinal variables).
