Cariogram multivariable caries-risk model (including modified/reduced-predictor versions) vs Alternative prediction model(s) within the same study, or no formal comparator (models compared descriptively; no between-model statistical test)

Predictive performance of the Cariogram for caries increment (positive likelihood ratio, LR+) · Children/adolescents (coronal caries) and older adults (root caries); populations from areas with varying caries risk

Modified Cariogram models showed modest positive likelihood ratios (LR+ ~1.1-3.8) for predicting caries increment, generally below the useful threshold; no pooled estimate; ungraded.

  • Multivariable prediction models of caries increment: a systematic review and critical appraisal. 2023 All outcomes
    Follow-up >=1 year (included studies 1-5 years) · Oral health care; children/adolescents and older adults; multiple countries · Model validation studies
    Six validation studies (5 coronal, 1 root) evaluated modified Cariogram models (not the original model per se). Review-stated LR+ range 1.1-3.8 (with one exception). LR+ was not substantially changed by excluding the…

Cariogram multivariable caries-risk model (including modified/reduced-predictor versions) vs Alternative prediction model(s) within the same study, or no formal comparator (models compared descriptively; no between-model statistical test)

Predictive performance of the Cariogram for caries increment (negative likelihood ratio, LR-) · Children/adolescents (coronal caries) and older adults (root caries); populations from areas with varying caries risk

Modified Cariogram models showed negative likelihood ratios of about 0.5-0.61, above the useful rule-out threshold; no pooled estimate; ungraded.

Original development of CAMBRA (Caries Management by Risk Assessment) or CAT (Caries-risk Assessment Tool) multivariable models vs Not applicable

Model development with reported performance measures (per CHARMS) · Individuals of any age at risk of caries increment

No original CAMBRA or CAT model-development studies reporting performance measures according to CHARMS were found (evidence gap); these tools appeared only as validated models within other studies.

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.

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.

Predictive performance for coronal caries increment (negative likelihood ratio, LR-) · Children and adolescents (aged 2-19) at risk of coronal caries increment (caries onset or progression)

Some developmental coronal-caries models achieved useful negative likelihood ratios (LR-<=0.20), but performance varied widely; no pooled estimate; ungraded.

    Follow-up >=1 year (included studies 1-5 years) · Oral health care; children/adolescents; no geographical restriction · Model development studies
    No meta-analysis. Per-model LR- (Table 2) for the 8 development studies ranged roughly 0.11-0.94 (e.g. Angulo 0.94, Demers 0.14-0.40, Gao 2010 0.11-0.30). Overall across all 66 models LR- ranged 0.0-1.1; LR-<=0.20…

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 coronal caries increment (positive likelihood ratio, LR+) · Children and adolescents (aged 2-19) at risk of coronal caries increment (caries onset or progression)

Most externally validated coronal-caries models showed modest LR+ (<5); only Campus 2012 and Gao 2013 NUS-CRA reached the useful threshold; no pooled estimate; ungraded.
