Rapid decline is defined as greatest quartile of decline in FVC over a mean of 2.9 years. Kaplan-Meier curves demonstrate the rates of (A) incident heart failure, (B) incident coronary heart disease, (C) incident stroke, and (D) the composite of these among the rapid decliner and non-rapid decliner groups. Hazard ratios (HR) and associated 95% confidence intervals are calculated from Cox regression models adjusted for age, sex, race, ARIC center, height, heart rate, body mass index, LDL-cholesterol, NT-proBNP, diabetes, hypertension, and smoking.
