Effect sizes of at least 0.20, at least 0.50, and greater than 0.80 correspond to small, medium, and large, respectively. Values are presented as mean ± standard deviation (SD). aUnivariate analysis of variance with Bonferroni correction P < 0.05 significant. bOne-sample t test. cGeneral linear model repeated measures with Bonferroni correction P < 0.05 significant. dP value significant after Bonferroni correction (P 0.05/10 = P = 0.005 = significant). SF-36 (Medical Outcomes Study 36-item Short-Form) dimension scores range from 0 to 100. Physical component score (PCS) and mental component score (MCS) are converted to mean 50 (SD 10). BP, bodily pain; GH, general health; ICU, intensive care unit; MH, mental health; PF, physical functioning; RE, role limitation due to emotional problems; RP, role limitation due to physical problems; SF, social functioning; VT, vitality.
