Patient selection.

<p>Fig 1 represented how to select and enroll the patients into analyses. Abbreviations are BMI: body mass index, ESRD: end-stage renal disease, PD: peritoneal dialysis, HD: hemodialysis and CRP: C-reactive protein.</p

Multivariate-adjusted odds ratios for all-cause mortality according to BMI categories.

<p>Odds ratios were calculated by logistic regression analysis adjusted for age, dialysis vintage, diabetes mellitus, serum albumin, phosphorus, CRP, creatinine and Kt/V. We used BMI of 20.0–22.9 kg/m² as the reference. Error bars indicated 95% confidence intervals. Abbreviations are OR: odds ratio, BMI: body mass index, CRP: C-reactive protein and Ref: reference group. ^ap, ^bp and ^cp denoted p values less than 0.001, 0.01 and 0.05 respectively.</p

Multivariate-adjusted odds ratios for all-cause mortality according to the BMI groups and the tertiles of serum Cr.

<p>We applied the group with normal-weight and the middle tertile of Cr as the reference. Abbreviations are BMI: body mass index, Cr: creatinine and Ref: reference group. ^ap, ^bp and ^cp denoted p values less than 0.001, 0.01 and 0.05 respectively.</p

Multivariate-adjusted odds ratios for the cause-specific mortality (A: cardiac death, B: cerebrovascular death, C: infection-related death, D: cancer-related death) according to BMI groups.

<p>We used BMI of 20.0–22.9 kg/m² as the reference group. Error bars indicated 95% confidence intervals. Abbreviations are OR: odds ratio, BMI: body mass index and Ref: reference group. ^ap, ^bp and ^cp denoted p values less than 0.001, 0.01 and 0.05 respectively.</p

Multivariate-adjusted odds ratios for the cause-specific mortality (A: cardiac death, B: cerebrovascular death, C: infection-related death, D: cancer-related death) according to BMI groups with serum Cr tertiles.

<p>We used the mortality rate of the group with normal-weight and the middle tertile of Cr as the reference. Abbreviations are BMI: body mass index, Cr: creatinine and Ref: reference group. ^ap, ^bp and ^cp denoted p values less than 0.001, 0.01 and 0.05 respectively.</p
