Fig. 10: Reproducibility of measurements between baseline and repeated measures in HELIOS.

Spearman correlation analyses were used to calculate the correlation coefficients between z-scored baseline and retest measurements (N = 398). Correlations are presented as box plots, where the upper bound marks the 75th percentile, and the lower bound marks the 25th percentile.
