  1. Repeated measures from Visit 1 (column 1) and Visit 2 (column 2) are presented for N = 56 participants that provided valid SST data at both visits. Reliability is assessed with Pearson correlation (r), paired t-test and intraclass correlation coefficient (ICC). Statistical significance was assessed at level of P < 0.05
