  1. HR = heart rate, bpm = beats per minute, Percent dehydrated = (post-weight- pre-weight)/ post weight *100. All data is expressed as mean ± standard deviation or median (range), depending on the results of the normality test (Shapiro-Wilks).
  2. *= Fisher’s exact test, † = Mann Whitney test, ‡= Wilcoxon signed rank test, all others unpaired.
