Data is expressed as mean ± standard deviation or median with interquartile range (IQR). Bold values denote statistical significance at p-value < 0.05.

*Significance values had been adjusted for multiple tests.

“–” The Dunn’s post hoc test was not performed if the overall test was not significant.
