Mean ± SD; n, sample number; I_MAX, maximum second moment of area; I_MIN, minimum second moment of area; Δ, percentage change in I_MAX or I_MIN shown in gray rows;

^a p<0.05 versus initial I_MAX value by a paired t-test;

^b p<0.05 versus gender- and genotype-matched initial I_MIN value by a paired t-test.
