Propensity Score Weighting Compared to Matching in a Study of Dabigatran and Warfarin

ConclusionsIn this example, different applications of the same PS led to substantially different results, a finding that was particularly apparent with IPTW, and this was remedied by truncating extreme weights. If IPTW is used, information regarding the weights applied along with sensitivity analyses could avoid misrepresentation of study results, and would enhance their interpretation.
