These biological parameters were measured using an automatic biochemistry analyzer (Hitachi 76000, Japan).
HCT: H = 4.38 (rank sum test); Ca2+: H = 2.21 (rank sum test); K+: H = 3.13 (rank sum test); Na+: H = 10.49 (rank sum test); Cl−: H = 10.34(rank sum test); HGB: F = 0.88 (ANOVA); CO2CP: F = 03.25 (ANOVA); ALB: F = 0.22 (ANOVA).
