Outcome this study informs	Pooled effect	Evidence	Certainty
Predictive performance for root caries increment (positive likelihood ratio, LR+) Multivariable prediction model of caries increment (>=3 predictors), e.g. logistic-regression or algorithm-based caries-risk models vs Alternative prediction model(s) within the same study, or no formal comparator (models compared descriptively; no between-model statistical test) · Follow-up >=1 year (included studies 1-5 years)	No meta-analysis. Development root-caries models from 2 root-specific studies (Ritter 2016 [22], Sanchez-Garcia 2011 [23]) plus Powell 1991 [21] (coronal and root). Per-model LR+ (Table 2): Ritter 1.81-2.23 (5 models),…	2 studies	Ungraded

Predictive performance for root caries increment (negative likelihood ratio, LR-) Multivariable prediction model of caries increment (>=3 predictors), e.g. logistic-regression or algorithm-based caries-risk models vs Alternative prediction model(s) within the same study, or no formal comparator (models compared descriptively; no between-model statistical test) · Follow-up >=1 year (included studies 1-5 years)	No meta-analysis. Per-model LR- (Table 2): Ritter 0.36-0.48 (5 models), Powell 0.20 (0.04-0.90), Sanchez-Garcia 0.86 (0.80-0.93). Powell reached the useful rule-out threshold (LR- 0.20).	2 studies	Ungraded
