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

ElementPlanned (methods)Found (results)
PopulationPeople of all ages in Ethiopia (irrespective of occupation and sex); English-language articles; studies conducted in Ethiopia from 2000 to 30 September 202013 cross-sectional studies; 6950 participants; age range 6-100 years; across 6 regions of Ethiopia (Amhara, Addis Ababa, Tigray, Oromia, SNNPR, Harar)
InterventionPrevalence of dental caries (no intervention); exposures for associated-factor analyses: sweet food consumption, dental plaque, tooth-cleaning habitPrevalence estimated; associated factors analyzed: sweet food consumption (4 studies), dental plaque (3 studies), tooth-cleaning habit (5 studies)
ComparisonNot applicable for prevalence; reference (non-exposed) groups for associated factorsReference groups: no/less sweet food consumption; absence of dental plaque; no tooth-cleaning habit
OutcomesPrevalence of dental caries (dichotomized present/absent by oral examination); associated factors reported >=3 studies expressed as adjusted odds ratiosPooled caries prevalence 40.98% (95% CI 31.62-50.34); associated-factor odds ratios: sweet food OR 2.4 (1.91-3.01), dental plaque OR 5.14 (0.67-39.39), tooth cleaning OR 0.71 (0.17-2.96)
Study designsObservational epidemiological (burden) studies conducted in Ethiopia (community-, school-, and hospital/clinic-based)13 cross-sectional studies; quality by Newcastle-Ottawa Scale (score >5/10) and Hoy et al. 10-item risk-of-bias tool for prevalence studies
TimingPrevalence assessed cross-sectionally; literature searched from 2000 up to 30 September 2020Included studies conducted between 2000 and 2020
