Figure 3. Subgroup Analyses for the Effect of 1-Month DAPT on the Primary End Point.

CREDO-Kyoto indicates Coronary Revascularization Demonstrating Outcome Study in Kyoto; HR, hazard ratio; PARIS, Patterns of Non-Adherence to Anti-Platelet Regimen in Stented Patients; STEMI, ST-segment elevation myocardial infarction. The vertical dashed line indicates the prespecified relative 50% noninferiority margin. Numbers and percentages shown are number of patients with event/number of patients at risk and incidences at 1 year. Acute coronary syndrome was the clinical presentation for the index percutaneous coronary intervention. Severe chronic kidney disease is defined as preprocedural estimated glomerular filtration rate less than 30 mL/min/1.73 m² or undergoing maintenance dialysis. See Table 1 for definitions of PARIS and CREDO-Kyoto risk scores.
