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

backgroundEarly Childhood Caries (ECC) is a common oral health problem that negatively affects their quality of life and everyday function. The Early Childhood Oral Health Impact Scale (ECOHIS) is a validated tool for measuring Oral Health-Related Quality of Life (OHRQoL) in preschoolers. Although the Persian version of ECOHIS exists, the relationship between dental caries and OHRQoL has not been sufficiently investigated in Iranian preschool populations. This study aimed to examine the association between ECC and OHRQoL in children aged 2 to 6 years within the PERSIAN birth cohort in Isfahan, Iran.

methodsA cross-sectional study was conducted between April and October 2023 on a subset of the PERSIAN birth cohort-Isfahan. A total of 350 children aged 2-6 years were initially recruited, of whom 347 were included in the final analysis. Clinical examinations were performed to record decayed, missing, and filled primary teeth (dmft) and parents completed the ECOHIS questionnaire. Children received oral health education and fluoride varnish. The association between dmft and OHRQoL was analyzed using chi-square tests, independent t-tests, and multivariate logistic regression, with adjustments made for confounding variables.

resultsHigher dmft scores were significantly associated with lower OHRQoL in both child and parent sections of the ECOHIS questionnaire (p < .001). According to multivariate logistic regression, each unit increase in dmft was associated with greater odds of low child OHRQoL (OR = 1.23, 95% CI: 1.16-1.31), low parent OHRQoL (OR = 1.32, 95% CI: 1.23-1.41), and lower parental satisfaction (OR = 1.35, 95% CI: 1.26-1.45). Household income was significantly associated with parent-reported OHRQoL (OR = 0.27, 95% CI: 0.12-0.61).

conclusionsDental caries were associated with lower OHRQoL of preschool children and their families. These findings emphasize the need for early detection, preventive strategies, and targeted oral health education, especially among low-income households. However, the results should be interpreted with caution due to the limited sample size, particularly within the moderate-income subgroup. Enhancement of public health initiatives and considering oral health in early childhood care programs may help reduce the burden of ECC and improve quality of life in this vulnerable population.
