Multivariable fractional polynomial graph for association of sST2 and sLR11 with study outcomes. Hazard ratios were calculated after adjustment for age, sex, peritoneal dialysis duration, diabetes mellitus, history of cardiovascular disease, smoking status, body mass index, and hemoglobin for all-cause death and MACCE. sST2 indicated a linear relationship with the risk of (a) all-cause mortality and (b) MACCEs. sLR11 did not show a remarkable trend with (c) all-cause mortality and (d) MACCEs. Shaded areas indicate 95% confidence intervals. Abbreviations: MACCE, major adverse cardiac and cerebrovascular event; sLR11, soluble form of low-density lipoprotein receptor relative with 11 ligand-binding repeats; sST2, soluble form of suppression of tumorigenicity 2
