Spearman’s (^anot normal distribution) and Pearson’s (^bnormal distribution) tests were performed to investigate the relationships between OST and quantitative patient characteristics. t-test was used to investigate the relationships between OST and qualitative patient characteristics. ^bData are presented as mean (± SD), as normally distributed
