Association between interdialytic weight gain and mortality by serum albumin subcategories (n = 8,661).a aEstimated from time-varying Cox regression models stratified by Dialysis Outcomes and Practice Pattern Study phase considering cluster effects by facilities, with restricted cubic spline (with 3 knots, P for nonlinearity <.001) adjusted for covariates (age, gender, renal disease, vintage, residual renal function, body mass index, comorbid conditions [hypertension, diabetes, coronary artery disease, congestive heart failure, other cardiovascular disease, cerebrovascular disease, lung disease, and malignancy] and laboratory measurements [hemoglobin, serum total calcium, serum phosphorus, single-pool Kt/V, and normalized protein catabolic rate]) and treatment time. Within each serum albumin subcategory, the hazard ratios were estimated with a reference interdialytic weight gain of 3% because serum albumin modified the association between the interdialytic weight gain and mortality (P for interaction <.001).
