P-values refer to the Spearman correlation test (adj.p for Benjamini-Hochberg procedure for multiple testing) for continuous variables and to the t-test (Welch test for unequal variances for the overall groups) for categorical variable. Bold values denote statistical significance at the p ≤ 0.05 level.
