B: regression coefficient from linear multiple regression; OR: odds ratio from multiple logistic regression; 95% CIs: bootstrap generated 95% confidence intervals. PLEASE NOTE: regression coefficients (linear regression) and odds ratios (logistic regression) were generated for continuous and binary predictors, respectively. For the categorical predictor ‘Body area’ (four categories), only p value was reported, indicating whether the means (for continuous outcomes) or proportions (for binary outcomes) differ significantly among the four groups constituted by the categorical variable.
