Long-term clinical outcomes between baseline Hb ≥ 100 g/l (reference group) and <100 g/l (a, c, e, g, i, k) or between time-averaged Hb ≥110 g/l (reference group) and <110 g/l (b, d, f, h, j, l). Outcomes: all-cause mortality (a, b), MACE (c, d), MACE+ (e, f), all-cause hospitalization (g, h), transfer to HD (i, j) and first episode of peritonitis (k, l). MACE includes myocardial infarction, unstable angina, stroke and cardiovascular deaths. Multivariable analysis adjusting for age, gender, annual income and serum albumin. *Inflammation status at baseline was defined as the baseline CRP >5 mg/l or hs-CRP >3 mg/l and inflammation status during follow-up was defined as more than half the time points for CRP >5 mg/l or hs-CRP >3 mg/l.
