Data are number (%), mean (SD), median [IQR], (min–max); comparison between clopidogrel versus aspirin+clopidogrel groups by χ² test, Kruskal-Wallis test or one-way analysis of variance.
Sixty-three participants recruited but 1 had no data collected.
BP, blood pressure; IHD, ischaemic heart disease; mRS, modified Rankin Scale; TIA, transient ischaemic attack.
