1 · What the graph read from it

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.

2 · The registry

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

objectivesOral health-related quality of life (OHRQoL) reflects the functional and psychosocial impacts of oral conditions on daily life. In low-resource settings such as rural Tanzania, limited access to dental care and preventive services may increase the burden of oral disease. This study assessed the association between clinical oral health conditions and OHRQoL among schoolchildren in rural Tanzania.

methodsA cross-sectional study was conducted among 293 schoolchildren at Igelehezda Primary School, Ilembula, Tanzania. Clinical examinations assessed dental caries using the DMFT index and oral hygiene using the OHI-S index. OHRQoL was measured with the Child Oral Impact on Daily Performances (C-OIDP) questionnaire. Behavioral data included sugar intake, number of daily meals, and toothbrushing-related symptoms. Associations between clinical, behavioral factors and OHRQoL were analyzed using descriptive statistics, bivariate tests, and multiple linear regression (

resultsAll 293 children completed the study (mean age 12.2 ± 1.2 years; 157 females, 136 males). Mean DMFT was 2.7 ± 4.1, with 80.5% free of untreated caries, and mean OHI-S indicated good oral hygiene (0.4 ± 0.6). Most participants were periodontally healthy (68.3%). Toothache, gum pain, or bleeding during brushing were reported by 26.0-31.6%. Eating was the most affected daily activity (42.7%). Missing teeth, toothbrushing-related symptoms, and consumption of high-sugar sweets were significantly associated with higher C-OIDP scores (

conclusionsMissing teeth, toothbrushing-related symptoms, and high sugar intake were associated with greater impairment in daily life, particularly affecting eating. These findings highlight the need for preventive and educational oral health interventions in rural, resource-limited settings.
