Clinical properties of objective items for complex regional pain syndrome

Data are presented as odds ratio (OR) or risk ratios (RR) (95% confidence interval). Com-RM, combined form of decreased range of motion and motor dysfuction; OR_crude, crude OR, derived from 2 by 2 contingency table; OR_adj, adjusted OR, derived from multivariate logistic regression analysis; RR, calculated according to following formula (Reference No. 18 and 19). RR = OR_crude / ([1-P₀] + P₀ × OR_crude) = OR_crude × (1-P₁) / (1-P₀). where P₁ = positive predictive value and P₀ = 1-negative predictive value. ^*P = 0.10.
