Time-related comparison of factor XI activity (FXI:C) in A, individuals in the acute VTE event and at 12 months of follow-up, and B, stratified by type of anticoagulant. In this figure panel A shows time-differences of FXI:C values available at acute VTE event and 12 months follow-up (n = 187). The p-value was derived from a paired t-test. Panel B shows time differences stratified by type of anticoagulant drug, in red for the acute VTE event and in blue for the 12 month follow up time point.
