Results from logistic regression analyses, modeling odds of a repeat VTE; now only for those patients whose first VTE occurred on or after 1 January 2015 (n = 584). Initial predictors (full model) were included based on univariate results. Final model includes only significant predictors after using backward elimination.
CI, confidence interval; OR, odds ratio.
