Patient characteristics for the whole group (n = 164) and the subgroups of patients that did not (n = 136) and did undergo recanalization therapy (n = 28).
Quantitative variables are expressed as mean ± standard deviation. Categorical variables are expressed as n (%). Test for differences between patients with recanalization vs. patients without recanalization: p-values are obtained from chi-square or fisher exact tests for categorical data and from Wilcoxon rank sum test for continuous variables.
