Atrial fibrillation risk according to bodyweight variability, stratified by a baseline body mass index and b overall bodyweight change. Bar graphs represent incidence rates per 1000 person-years with scales on the left. Line graphs with error bars represent the hazard ratios with 95% confidence intervals for atrial fibrillation development with scales on the right. Hazard ratios were adjusted for baseline body mass index, age, sex, smoking, drinking, exercise, low income, hypertension, dyslipidemia, number of oral anti-diabetic medication, insulin use, duration of diabetes, and fasting glucose.
