Figure 1.

Median boxplot of group differences in IHI from left to right M1 between musicians (gray) and non-musicians (black). On each box, the horizontal line represents the median, the upper and lower edges the 75th and 25th percentile, the whiskers show the range, and red “+”s indicate statistical outliers. Musicians were subdivided into pianists (n = 7) and string players (n = 8) and plotted separately within the gray box. Significant group differences are denoted with ^*(p < 0.05, corrected for multiple comparisons).
