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
purposeThe first molars are frequently the first permanent teeth to erupt in the oral cavity, and their premature loss can significantly affect a child's oral health. This study aimed to identify determinants of dental caries on the first permanent molars among schoolchildren.
methodsA longitudinal study was conducted with 122 mother-child pairs from the Brazilian city of Diamantina. The children were evaluated at three instants: first, between 1 and 3 years of age (T1), then, 3 years after the initial assessment (T2), and finally, 6 years after the initial assessment (T3). Socioeconomic data, child habits, visible plaque, and dental caries (assessed through International Caries Detection and Assessment System [ICDAS-II]) were collected at all three time points.
resultsThe incidence of dental caries in the first permanent molars was 70.5% and was associated with the presence of caries at T1 (RR = 1.41; 95% CI 1.08-1.84) and T2 (RR = 1.58; 95% CI 1.12-2.22). The following variables at both T1 and T2 were also significantly associated with caries incidence: a high number of income dependents (RR = 1.66; 95% CI 1.17-2.35) and low brushing frequency (RR = 1.77; 95% CI 1.27-2.46). Yet, the persistence of low brushing frequency from T2 to T3 (RR = 1.32; 95% CI 1.05-1.65) was also associated with the incidence of caries.
conclusionsThe incidence of dental caries in the first permanent molars was associated with prior caries experience, low toothbrushing frequency, and schoolchildren belonging to families with a high number of income dependents. These findings highlight the importance of early preventive interventions and socioeconomic considerations in addressing childhood dental caries.
