Additional file 2 of Impact of serum sodium concentrations, and effect modifiers on mortality in the Irish Health System

Additional file 2: S2 Fig. Adjusted relative mortality risk associated with Na+ levels by eGFR category. Red solid line (—) denotes Hazard ratio and dash line (- - -) denotes 95% confidence intervals (CIs) for eGFR ≥ 60 ml/min/1.72m2. Blue solid line (—) denotes Hazard ratio and the ribbon denotes 95% confidence intervals (CIs) for eGFR < 60 ml/min/1.72m2. Hazard ratios were adjusted for age, sex, serum albumin, haemoglobin, serum potassium, serum calcium, white blood cell count, alanine aminotransferase, alkaline phosphatase, and clinical location at baseline and an interaction term between serum sodium and eGFR was included.
