Prior use of therapeutic anticoagulation does not protect against COVID‐19 related clinical outcomes in hospitalized patients: a propensity score‐matched cohort study

Retrospective Dutch study (n=1154) found no associations between prior therapeutic anticoagulation use (16% of population) and mortality (RR 1.02; 95% CI; 0.80‐1.30) or length of hospital stay (7.0 vs 7.0 days, p=0.69), except lower risk of pulmonary embolism (0.19; 0.05‐0.80).
