*a*The correction of*P*values for multiple testings was performed by considering each test as a family of tests. The*P*values were analyzed and adjusted according to the method of Hommel (31); corrected values are in parentheses. Ranges of calculated*P*values: *,*P*> 0.1; **, 0.1 >*P*> 0.05; ***, 0.01 <*P*< 0.05; ****,*P*< 0.01.↵

*b*The percentage of cells <5 refers to a common benchmark for the validity of χ^{2}analysis.
