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.

Impaired OHRQoL measured with CPQ 11-14 (quantitative synthesis / meta-analysis) · Adolescents (10-19 years)
Malocclusion (DAI) probably increases the prevalence of impaired OHRQoL (CPQ 11-14) by about 15% in adolescents (RR/PR 1.15, 95% CI 1.12-1.18; moderate certainty).
