Adjusted hazard ratios for all-cause mortalityby serum sodium stratified by clinincal setting at baseline Solid line (—) denotes Hazard ratio and dash line (-—-) denotes 95% confidence intervals (CIs). Filled circles denote statistical significance (P < 0.05) compared with the reference (blue circle). Estimates are based on adjusted penalised spline models for the association between time dependent serum sodium and all-cause mortality. Hazard ratios were adjusted for age, sex, estimated glomerular filtration rate, serum albumin, haemoglobin, serum potassium, serum calcium, white blood cell count, alanine aminotransferase, alkaline phosphatase
