The WS value according to extracellular water (ECW) to total body water (TBW) as assessed by bioimpedance analysis. Normal condition indicates an ECW to TBW ratio < 0.390 (n = 178), mild overhydrated condition indicates an ECW to TBW ratio 0.390–0.399 (n = 118) and moderate to severe overhydrated condition indicates an ECW to TBW ratio ≥0.400 (n = 58). Missing data for the ECW to TBW ratio, n = 2.
