Association between baseline body mass index and all–cause mortality in 20,818 Korean hemodialysis patients†

†Hazard ratios were estimated with Cox regression using restricted cubic splines. Values of <1 percentile and >99 percentile in body mass index were excluded from the model to minimize an influence from the outlier values. The model was adjusted for case–mix and nutrition covariates including age, gender, diabetes mellitus, dialysis vintage, single–pool Kt/V, hemoglobin, serum albumin and normalized protein nitrogen appearance. Dashed lines are 95% point–wise confidence bands. Number of patients is displayed simultaneously.
