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
Background Dental caries is a chronic, multifactorial, and preventable disease caused by cariogenic bacteria, fermentable carbohydrates, host factors (saliva and tooth structure), and time. In Mexico, it is a public health problem, exacerbated by the lack of access to dental care. The first permanent molar (FPM), key to occlusion and mastication, is vulnerable to bilateral caries, suggesting systemic or environmental influences. Studying its bilateral pattern would help optimize preventive strategies, especially in marginalized populations with limited resources. This study aimed to determine the prevalence of caries and bilateral occurrence in the FPMs of a sample of Mexican schoolchildren, as well as to describe the Care Index and treatment needs. Methods A cross-sectional study was conducted. A total of 428 FPMs from 107 children (5-12 years) treated at a pediatric dental clinic of a public university in Mexico, which provides specialized services at low cost to the general population, were evaluated. The decayed, missing, and filled teeth index, the Care Index, and the Treatment Needs Index (TNI) were recorded. Symmetry tests (Stuart-Maxwell) were used to analyze bilaterality. Data were processed with Stata 14.0 (StataCorp LP, College Station, TX, USA). Results Of the total, 50.5% were boys, and the average age was 8.52±1.36. A total of 58.9% of children presented caries (overall decayed, missing, and filled teeth index: 1.90±2.01; in FPMs: 1.71±1.74), and 57.0% presented at least one affected FPM. It was observed that 43.0% had no caries experience in their four FPMs, and 28.0% had caries experience in all FPMs. The Care Index was 42.7%, and the TNI was 67.4%. The percentage of bilaterality was 84.1% for upper molars and 81.3% for lower molars. There were no significant differences in caries bilaterality between upper (p=0.1969) and lower (p=0.3896) molars, suggesting symmetry in the involvement. Conclusions Bilaterality was observed in the caries experience of the lower molars in this sample. Approximately one in four children had caries in their four FPMs. The high prevalence of caries and treatment needs underscores the urgency of affordable, preventative interventions, especially in vulnerable populations.
