Plot of the correlation between individual phone length and HAMD score. Blue indicates a positive correlation; red a negative correlation. The size of the circle marker is scaled by the magnitude of the correlation. Only significant correlations (p-value < 0.05) are shown. Correlation coefficient range: max marker = 0.47; min marker = 0.19. Correlation results with pause length are included for comparison.
