Absolute changes in the ECW/TBW depending on high vs. low ECW/TBW and the BNP at baseline. a The absolute change in the high-ECW/TBW group (over the median value of 0.413, n = 18) were significantly higher than those in the low-ECW/TBW group (less than the median value of 0.413, n = 18). b The absolute change in the high-BNP group (over the median value of 95.7 pg/mL, n = 14) were significantly higher than those in the low-BNP group (less than the median value of 95.7 pg/mL, n = 13). ECW extracellular water, TBW total body water. *p < 0.05 vs. low-ECW/TBW group or low-BNP group
