ESPRIT (European/Australasian Stroke Prevention in Reversible Ischaemia Trial)
Results
Subgroup Analysis
The following figure shows the results of the planned and post hoc defined subgroup analyses for the primary outcome event. The investigators noted no major differences between subgroups (smallest p value for interaction 0.18). Because all patients from non-Asian countries (with the exception of 3 patients from hospitals in Portugal, where extended-release dipyridamole is not available) used slow-release dipyridamole, the group did no additional analysis for this type of preparation.
