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: Untreated dental caries is a leading cause of poor oral health and has a significant impact on quality of life. This study aimed to assess the effect of dental caries on oral health-related quality of life (OHRQoL) among secondary school students in Kigali, Rwanda. Methods: An analytical quantitative cross-sectional study was conducted among 646 students aged 12-21. Socio-demographics, oral hygiene, and caries experiences were collected. The oral impact on daily performance score was used to assess oral health-related quality of life. Binary analysis and multiple logistic regression were performed to investigate the association between variables and dental caries. Results: The study found a moderate DMFT index (3.3 ± 3.9), with decayed teeth at 61.1%. Daily activity affected more than 91% of participants, pain affected 35%, and dissatisfaction with oral health, 58.5%. Participants aged 15-19 years had a higher prevalence of dental caries (AOR 3.3, P=0.03), the same as those who did not brush (P<0.001), chewing foods (P<0.001), or missed school (P<0.001). The OIDP scores were greater among rural residents (P=0.001). Conclusion: The prevalence of dental caries was moderate. It significantly affected students' social, emotional, and physical well-being. These findings emphasize the need for targeted interventions to improve oral health and its impact on students' quality of life.
