Calculations were performed for the complete dataset (All data) and the two best-fitting panels (RM and L; abbreviations as in Table 1) and three summary statistics (median, mean and mode). Regression coefficients (Beta) and their 95% confidence intervals are reported for all models, while p-values and R-squared statistics (M = Multiple, A = Adjusted) only for regressions with intercept.
