Fig. 2

The conceptual and statistical framework of potential interactions tested in the predictive models. Arrows indicate the direction of prediction. Red circles represent the predictor (lesion characteristic) used in univariate models (#1–#5). Signal “+” symbolizes the interaction of individual variables or combination using dummy variables. Solid lines/symbols indicate the interactions considered for modelling considering a priori conceptual framework and the statistical appreaciation of AIC (Models #6–#13). Predictors with lower AICs-surface integrity (orange symbols) and texture (green symbols)- were combined to produce interactions with other relevant predictors to permit estimating their combined effect on predicting caries progression. Dashed lines/symbols indicate those interactions which could potentially exist in the conceptual framework, but they were not presented in our Results for statistical options guided by the AIC values
