Median (minimum–maximum) for not-normally distributed data and means± s.d. for normally distributed data are presented. Different letters indicate statistical differences between values in the line. F,statistic value of one-way ANOVA. H, statistic value of Kruskal–Wallis one-way ANOVA on ranks. See Fig. 3B for definition of measured parameters
