Measure
Type 2 Diabetic Patients
n=20 Participants
All participants receive both Ticagrelor and Clopidogrel (each with aspirin) in a cross-over design. Treatment sequence (Tica-Clop OR Clop-Tica) was randomly assigned and with a 2-week washout period in between (i.e., "Tica/Clop (5-7 days)", "Washout (14 days)", and "Clop/Tica (5-7 days)").
