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
aimTo evaluate and compare tooth surface pH and salivary pH at various time intervals using different directives of sports drink and mouthguard among adolescents involved in contact sports. METHODOLOGY: This study involved 125 athletes aged 10-19 years, each provided with a mouthguard customized to their dentition. During a 40-minute physical activity session, participants consumed a sports drink either with or without water and with or without a mouthguard at 10-minute intervals. Salivary and tooth surface pH levels were recorded at baseline and at each break. The study was conducted over four consecutive weeks in four phases- Phase 1 (Sports drink without mouthguard), Phase 2 (Sports drink and water without mouthguard), Phase 3 (Sports drink with mouthguard), Phase 4 (Sports drink and water with mouthguard), altering the directives for sports drink consumption and mouthguard use. Data was analysed using Power BI and Python 3.11.4, with one-way ANOVA and Tukey's post hoc test for statistical comparisons.
resultsThe results demonstrated that wearing a mouthguard helped maintain tooth surface and salivary pH stability when consuming sports drinks, with or without water. In contrast, without a mouthguard (phases 1 and 2), a significant pH drop was observed (p < 0.05), particularly at 20 and 30 min, though partial recovery occurred with water intake.
conclusionThe study underscores the dual role of mouthguards, that is, not only their well-established benefit in preventing dental trauma, as reported in previous studies, but also their potential function as a protective barrier against acid-induced enamel demineralization. However, further well-designed studies are required to confirm and substantiate these beneficial effects of mouthguard use. CLINICAL SIGNIFICANCE: The findings of this study provide clear guidelines for the safe consumption of sports drinks among adolescent athletes, while also emphasizing the dual role of mouthguards in preventing both dental trauma and the erosive effects of these beverages.
