All analyses on strata were adjusted for age, sex, dialysis vintage, allocated treatment (excluding the conventional risk factor of the stratum under study), and presence of DM, CVD, and RKF. Estimates in this table may differ slightly from estimates in the text of the Results, because estimates in this table are derived from models performed in the subgroups separately. LnIL-6, natural logarithm of IL-6.

a

Estimate slope indicates the mean longitudinal change per year in LnIL-6 levels associated with the presence or absence of the conventional risk factor, the percent change per year calculated by eΔLnIL6.

b

Versus RKF (no difference hemodialysis and hemodiafiltration).
