Coordination function in the P22–30 cohort of C57BL/6N, DBA/2, and FVB/N strains. (a) The grip strength test revealed increased grip strength for FVB/N mice compared to C57BL/6N and DBA/2 mice. (b) The beam balance rod test showed no difference between the three investigated strains. (c) DBA/2 mice displayed the lowest latency to fall off the grid in the inverted screen test. (d) In the cliff avoidance reaction test, DBA/2 mice exhibited the lowest latency to fall off the cliff (left) and the highest number of falls (right) compared to C57BL/6N and FVB/N mice. Two-way ANOVA followed by Tukey post hoc test, *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001. A black rectangle indicates a significant difference between sexes within a strain (see Supplementary Table 2). Blue and red dots refer to males and females, respectively. Error bars indicate the standard error of the mean (SEM).
