These factors were evaluated using 12 linear mixed models: one for each type of feature and frequency band. Columns indicate R2 value and direction of correlation (positive, negative, higher for men than women). P-values are indicated by symbols and are uncorrected for multiple comparisons. ***p < 0.001, **p < 0.01, *p < 0.05, N.S. (–), p > 0.05.
