  1. Values are shown as the mean ± standard deviation (SD)
  2. *There was statistically significant difference between OH and MH groups, P < 0.05
  3. †There was statistically significant difference between MH and HH groups, P < 0.05
  4. ‡There was statistically significant difference between OH and HH groups, P < 0.05. The One-way ANOVA was used to compare the differences among the three groups, including males and females. When comparing the differences between males and females within the group, Student’s t test was used. Differences were found in the concentrations of Na (F = 7.075, P = 0.001). In OH group, the concentrations of Na and Ca were different between males and females (t = − 3.411, P = 0.001; t = − 4.488, P < 0.001); in MH group, differences were found in the concentrations of phosphate and Mg (t = 3.472, P = 0.001; t = − 2.427, P = 0.018); and in HH group, differences were found in the concentrations of Na and phosphate between males and females (t = − 2.849, P = 0.009; t = 3.050, P = 0.006)
