Statistics for the regression analysis including the model fit of models achieving a maximum R2 and minimum root mean square error (RMS);
* represent the level of significance (n.s.: not significant for p ≥0.05, *: p <0.05, **: p <0.01, ***: p <0.001); the numbers indicate the degree of terms included in the model for maximum R2 (1linear terms, 2quadratic terms); PDQx indicates the respective of the eight items of the PDQ-8 questionnaire.
