Normally distributed data expressed as mean ± SE
Non-parametric data expressed as median (min-max).
Superscript capital letters (A, B) denote significant differences between groups with different letters where a p-value <0.05 is considered significant
No superscript letters in a row indicates no significant differences between groups for the measured parameter
