  1. Note: Results are presented as Theta with a 95% Credible Interval (CI), with the probability of the Theta being above 0: Pr(Theta> 0). A large Pr(Theta> 0) value (e.g., > 0.95, > 0.975, or 0.99) must be interpreted as indicating lower values for patients compared to controls (for predictor group). A small value of Pr(Theta> 0), for instance, < 0.05, 0.025, or 0.01, reflects higher values for patients compared to controls. It is worth noting that the probability Pr(Theta> 0) can be interpreted as 1 Pr(Theta< 0). Thus, probability values near 1 and 0 both indicate a significant effect
