Multivariable caries prediction model vs Alternative prediction model(s) within the same study, or no formal comparator (models compared descriptively; no between-model statistical test)
Predictive performance for root caries increment (positive likelihood ratio, LR+) · Older adults (aged 52-95; mean 52-73) at risk of root caries increment
Developmental root-caries prediction models were generally modest, except Sanchez-Garcia 2011 (LR+ 7.09) which reached the useful threshold; no pooled estimate; ungraded.
