  • Outcome was all-cause mortality; predictors were categories of low (<10th percentile) and high (>90th percentile) LTI and FTI, respectively. Models were adjusted for age, vintage, and sex or as otherwise indicated. LTI, lean tissue index; FTI, fat tissue index; reference, normal LTI and FTI (10th–90th percentile of age- and sex-matched healthy population); HR, hazard ratio; 95% LCI, lower 95% confidence interval; 95% UCI; upper 95% confidence interval.

  • a Adjusted for age, vintage, sex, geographic region, albumin, hemoglobin, diabetes, and BP.
