Standardized mean differences for the pseudonymized and anonymized real-world and randomized clinical trial data sets. Standardized mean differences are shown for prior to matching, after matching, after matching weighting, and after overlap weighting groups. Values for the anonymized set that are not visible are approximately equal to the pseudonymized ones. BMI, body-mass index (kg/m2); COPD, chronic obstructive pulmonary disease; MW, matching weighting; NOAC, novel oral anticoagulant; OW, overlap weighting; RWD, real-world data; SMD, standardized mean difference; SSRI, selective serotonin reuptake inhibitor; TIA, transient ischemic attack
