The wilcoxon signed rank test was used for statistical analysis, pre: before water intake, post: after water intake.
SD, standard deviation; WBC, white blood cell; RBC, red blood cell; Hgb, hemoglobin; Hct, hematocrit; MCV, mean corpuscular volume; MCH, mean corpuscular hemoglobin; Plt, platelet; MPV, mean platelet volume.
