Univariate analyses of risk factors associated with thromboses and hemorrhage of any grade. Risk factors associated with thromboses (A) and risk factors associated with hemorrhages (B) are reported. Single comorbidities and CVRFs were tested and were not associated with TRA failure: hypertension (P = .89), overweight (P = .61), dyslipidemia (P = .81), smoking (P = .67), diabetes (P = .97), solid neoplasia (P = .18), acute myocardial infarction (P = .22), peripheral vascular disease (P = .08), chronic kidney disease (P = .56), chronic obstructive pulmonary disease (P = .21), liver disease (P = .68), peptic ulcer (P = .46), congestive heart failure (P = .58), and transient ischemic attack/stroke (P = .39) (data not shown). Multivariable analyses were not carried out because only 1 covariate had a P value < .10 in univariate analyses.
