PF-10 = SF-36 physical functioning scale; HAQ-SDI = Health Assessment Questionnaire standard disability index; HAQ-ADI = Health Assessment Questionnaire alternative disability index; ES = Cohen’s d effect size; F = F-statistic from one-way ANOVA; RV = Relative validity (ratio of F-statistics compared with observed score); 95% CI = 95% bootstrap bias-corrected and accelerated confidence interval.
