All data were checked for normality and homogeneity of variances
using Shapiro–Wilk’s and Levene’s tests, respectively.
Comparisons of data from different treatments were performed
by a one-way analysis of variance (ANOVA) and significantly different
treatments were identified by Dunnett’s test. Pearson correlation
coefficient was applied to test correlations between different
endpoints. All differences were considered significant at p < 0.05.
Statistical analyses were performed using the SPSS statistical
package.
