Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.

Review question

PopulationChildren with deciduous and/or permanent dentition, no age limit, residing in low- and middle-income countries (World Bank definition)11 studies; 11,115 children from six LMICs (Brazil, Nigeria, Cambodia, Tanzania, Mexico, Ethiopia); data from 2001 to 2022
InterventionChild-, family-, and socioeconomic-level factors (exposures/risk factors) reported as prevalence: e.g., gender, feeding, diet/sugary intake, oral hygiene/brushing, maternal age and education, caregiver help with brushing, fluoride toothpaste, SES, setting, access to dental servicesFactors meta-analyzed (n varies per analysis): sugary drinks/sweets, good brushing habits, maternal education (no formal/primary/secondary+), caregiver help with tooth brushing, fluoride toothpaste, SES (low/middle/high), access to dental services, female sex
ComparisonChildren with versus without dental caries (association/odds-ratio analyses); none for single-group prevalence estimatesChildren without dental caries (association analyses); single-group proportions among children with caries (prevalence analyses)
OutcomesDental caries (presence/absence in primary or permanent dentition; dmft/DMFT, or ICDAS II)Caries prevalence 38.7% (95% CI 28.4-49.5%; 11 studies). Associations with caries: sugary drinks OR 2.04 (1.59-2.60); good brushing OR 0.65 (0.46-0.92); primary maternal education OR 1.25 (1.02-1.54); secondary+ education OR 0.96 (0.64-1.44); no formal education OR 1.34 (0.76-2.36); caregiver help OR 0.35 (0.13-0.93); low SES OR 1.52 (1.22-1.89); middle SES OR 0.80 (0.59-1.10); high SES OR 1.03 (0.81-1.31)
