↵* Significant p values for comparisons between scores for the given category and SSc using a standard 2-sample t-test.
↵† Significant p values for comparisons using a one-sample Wilcoxon test to account for non-normality. Both utilize a simple Bonferroni correction for multiple comparisons to maintain a family-wise type I error rate of < 0.05. PCS: physical component summary, MCS: mental component summary.
