Evaluating prophylactic heparin in ambulatory patients with solid tumours: a systematic review and individual participant data meta-analysis

Meta-analysis of individual participant data from 14 of 20 eligible RCTs (n=8278) found LMWH was associated with a lower VTE risk (adjusted RR 0.58; 95% CI 0.47-0.71), but there was no survival benefit. Risk of minor bleeding (1.34; 1.19-1.51), but not major, was increased.
