Values for multiplicity are expressed as means ± SD. Incidences were generally assessed by Chi-square test, followed by pairwise analysis with Bonferroni correction. Multiplicities were generally analyzed by ANOVA, followed by the Tukey test for multiple comparison. aP < 0.01 vs. Group B, bP < 0.01 vs. Group A, cP < 0.05 vs. Group A, dP < 0.05 vs. Group C, eP <0.05 vs. Group B.
