Fig. 2: Caterpillar plots of posterior estimates of varying coefficients of sound level and their 60% credible interval in the empirical Bayes model.

The vertical dashed line is the fixed effect coefficient while the horizontal blue lines indicate the random effects of sound level on physiological wellbeing across participants. a Caterpillar plot for sound level <50 dBA, and b the plot for sound level >=50 dBA.
