Table 4 the predictors of the bracing outcome determined by a regression model with regularization. For the interaction terms, a positive coefficient shows an increase in the one variable also increased the effect of other variable on the outcome (Progressed group) whereas a negative coefficient suggest that an increase in a variable decreased the effect of other variable on the outcome. Coefficients shown are partial regression coefficients
