Simplified caries prediction models (>=2 predictors; microbiome-primary studies excluded), but some pooled models include microbe predictors (Yaxuan 2023: S. mutans; Kim 2018: biofilm acidogenicity/saliva) vs No competing model

Model discrimination (area under the ROC curve, AUC) · Children and adolescents aged 1-18 years

Simplified childhood caries prediction models show moderate pooled discrimination (AUC 0.79, 95% CI 0.73-0.84) but with very high heterogeneity (I2=97.3%) and all models at high risk of bias (PROBAST); ungraded.
