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
objectivesThis in vitro study aimed to evaluate the effect of different application protocols of surface pre-reacted glass-ionomer (S-PRG) sealant on penetration ability, retention, and occlusal caries inhibition, in comparison with resin-based sealant (RBS) under simulated oral conditions. MATERIALS AND
methodsEighty-four extracted human third molars were randomly assigned to five groups: S-PRG sealant applied per manufacturer's instructions (G1), S-PRG with 37% phosphoric acid etching pretreatment (G2), S-PRG with fluoride varnish pretreatment (G3), RBS (G4), and a no-sealant control (G5). Sealant retention was assessed through visual inspection following water storage at 37 °C and thermocycling, whereas penetration depth was evaluated using scanning electron microscopy (SEM). Caries inhibition was evaluated via mineral density changes (ΔMDV) measured by micro-CT after 21-day pH cycling and Streptococcus mutans bacterial challenge. Statistical analysis included Kruskal-Wallis tests, Mann-Whitney U tests with Bonferroni correction, Chi-square tests, Spearman's correlation, and multiple linear regression analyses.
resultsNo statistically significant differences in sealant retention were found among the groups. RBS (G4) exhibited the highest median penetration (100%), followed by G2 (85.0%), G1 (59.5%), and G3 (44.5%), with significant differences among specific pairwise comparisons (p < 0.001). No significant difference in ΔMDV were observed in pH cycling, but bacterial testing revealed significantly lower ΔMDV in G2 and G4 compared to G3 and G5 (p ≤ 0.005).
conclusionsS-PRG sealants pretreated with phosphoric acid etching demonstrated significantly greater caries inhibition effects compared to using self-etched primer alone, and its caries prevention efficacies were comparable to that of RBS. CLINICAL RELEVANCE: These in vitro findings support the use of phosphoric acid etching to enhance the performance of S-PRG sealants.
