Oral Health on Sal, Cape Verde: A Population-Based, Cross-Sectional Study.
Article in International dental journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesSal is one of the ten islands of Cape Verde, a lower-middle-income country in Africa. Local reports suggest poor oral health among residents, but no scientific data exists. This study aimed to assess oral health status and oral health-related quality of life (OHRQoL) of Sal's dentulous inhabitants, identify risk factors associated with oral health, and explore correlations between oral health and OHRQoL in adults. MATERIALS AND
methodsA population-based cross-sectional study was conducted among dentulous Sal residents. Final-year dental students from the Academic Centre for Dentistry Amsterdam (ACTA), Faculty of Dentistry in Amsterdam, performed duplicate oral health examinations. Outcomes included caries experience (dmft/DMFT), consequences of untreated caries (pufa/PUFA), and periodontal health (DPSI; in adults only). Data on brushing frequency, toothbrush ownership, toothpaste availability, dental visits, dental insurance, and tobacco use (adults only) were collected. Adults completed the OHIP-14 questionnaire (OHRQoL). Descriptive statistics summarized characteristics; multivariable regressions assessed associations.
resultsA total of 1,371 dentulous residents participated (609 children aged 1-17 years; 762 adults aged 18-89 years). Caries prevalence was 87.5% and pufa/PUFA 52.2%. Mean dmft/DMFT was 3.7 ± 3.2 (children) and 7.5 ± 6.2 (adults). 63.1% had DPSI maximum-scores ≥3+ (periodontal disease). Toothbrush ownership was high (>96%), access to toothpaste (<90%) and dental insurance was limited (children 63%; adults 46%). Dental insurance was associated with lower dmft/DMFT (p = .019) and lower pufa/PUFA (p = .005). Higher DMFT, PUFA, and severe periodontal disease was associated with poorer OHRQoL. CONCLUSIONS AND CLINICAL RELEVANCE: Oral health among Sal's residents is poor, with a high disease burden and limited access to care. Improving preventive strategies and access to dental services is important to reduce disease prevalence and enhance quality of life.
