- Logistic or linear multivariate regression including variables shown plus age, FEV1/FVC, height, race, education, and smoking. *p = 0.077
- Results are for 1 kg increment in lean or fat mass OR per 1 cm increment in SAD
- Lean massresid = residual variable for lean mass removing the contribution of fat mass and height;
- SADresid = residual variable for sagittal abdominal diameter removing the contribution of lean mass and fat mass (see Methods)
