Body mass index categories and erector spinae muscle abnormality in patients with COPD. A. Distribution of overweight, normal-weight, and underweight patients with COPD in the Kyoto–Himeji cohort. Overweight: body mass index (BMI) ≥ 25 kg/m2; normal weight: BMI ≥ 18.5 kg/m2; underweight: BMI < 18.5 kg/m2. B.: The prevalence of erector spinae muscle (ESM) abnormalities, such as low ESM area (ESMA) and density (ESMD) among patients with COPD stratified by BMI. C, D. Representative normal-weight patients with low and normal ESMD despite similar ESMA
