Abbreviations: BMI, body mass index, CrI, credible interval; FMI, fat mass index; HR, hazard ratio; LMI, lean mass index.

^a For each model, the logit of proportion of body fat was specified as a function of age, race, sex, and smoking status, which was then used to calculate the LMI (lean tissue (kg)/height (m)²) and FMI (adipose tissue (kg)/height (m)²).

^b Priors for proportion of body fat model used parameters in Table 2.

^c Priors for proportion of body fat model as in model 1 with mean for BMI coefficient multiplied by 0.90.

^d Priors for proportion of body fat model as in model 1 with residual error multiplied by 1.10.

^e Hazard ratios per unit increase, adjusted for age (continuous), sex, race, years smoked (0, 1–9, 10–19, 20–39, 40–49, ≥50), lifetime alcohol intake (nondrinkers and, in mL: ≤133,294, 133,295–747,550, ≥747,551), total intake of fruits (continuous), total intake of vegetables (continuous), number of comorbidities reported (cardiovascular disease, pulmonary disease, renal disease, diabetes, and other cancers), and stage (I/II vs. III/IV).
