Fig. 1From: Patient-reported symptoms during dialysis: the effect of pre-dialysis extracellular water and change in extracellular water post-dialysisDialysis symptom frequency scores using a visual analogue scale of 0 to 10. Patients divided according to extracellular water to height ratio into 3 groups—lower, middle, and higher tertiles. Results expressed as median, interquartile, and 90% limits. *p < 0.05, **p < 0.01, ***p < 0.001 vs those in the lower tertileBack to article page
