Base model: adjusted for clustering of patients within hospitals. Age: continuous variables. Hospital grade: second hospital or tertiary hospital. Socioeconomic status: marriage status and occupation. Cardiovascular risk factors: hypertension, dyslipidemia, diabetes, and current smoker. Medical history: a medical history of coronary heart disease, heart failure, stroke, and chronic kidney diseases. Clinical characteristics: myocardial ischemia symptoms, heart rate, systolic blood pressure, Killip class, cardiac arrest, and anterior myocardial infarction at admission. Time to present: time from symptom onset to first medical contact at the hospital. Acute drugs: aspirin, P2Y12, and statin at emergency. Reperfusion therapy: successful reperfusion or not. Percent of sex difference account: (OR−unadjusted OR)/(unadjusted OR−1.0)100%.
