Summary of Villalta and postthrombotic syndrome (PTS) severity outcomes. At 1-year follow-up, patients in the CLOUT registry had significant reductions in (A) median Villalta score and (B) PTS severity when compared with baseline. Most patients (80.7%) had no PTS 1 year posttreatment, whereas 8.8% had moderate or severe PTS. Boxes represent IQR (Q1, Q3) with horizontal bars representing median values and vertical lines representing 1.5× (Q1-Q3). P values comparing values between baseline and 1-year visit derived from the Wilcoxon signed-rank test for the Villalta score and the McNemar-Bowker test for PTS severity.
