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 (negative likelihood ratio, LR-) · Older adults (aged 52-95; mean 52-73) at risk of root caries increment
The single root-caries validation study (Hayes 2017) showed LR- of 0.34-0.41, above the useful rule-out threshold; no pooled estimate; ungraded.
