Fig. 2

No age and gender differences in the modified Rotarod test analyzed by 4 parameters. A 4-parameter read-outs in Trial 2 at baseline testing in young adult males (10–14 wks, n = 19, solid symbols) vs. middle-aged males (31–38 wks, n = 7, hollow symbols). B 4-parameter read-outs in young-adult female mice (21 wks, n = 7, solid symbols) vs. middle-aged (47–54 wks, n = 7, hollow symbols) females. C 4-parameter read-outs for adult males (n = 28, solid symbols) vs. females (n = 18, hollow symbols). First latency and Longest duration are shown in seconds (s) on the left Y axis, Maximal distance is shown in centimeters (cm) on the first right Y axis and Number of falls is shown in on the last Y axis. Statistical evaluations were done by the Kruskal-Wallis test followed by Dunn’s correction for non-matched and non-parametric data. The p-values obtained from the analysis were greater than 0.99, indicating no significant difference among the groups
