Numerical data are presented as the mean SD.
After KolmogorovSmirnov normality testing, parametric data were analyzed by one-way repeatedmeasures analysis of variance and the HolmSidak post hoc test to compare the changes in each parameter for each group. Nonnormally distributed data were analyzed by one-way repeatedmeasures analysis of variance on rank, followed by Dunn’s test. Student’s t-test or MannWhitney U test was performed after the normality test to compare groups at the same time point. Significance was set at P 0.05.
