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
Given the increasing use of three-dimensional (3D) technology, evaluating the effects of prolonged brushing on denture base resins is necessary. This study evaluated the influence of long-term brushing with cleaning/disinfection agents on the surface properties of heat-cured and 3D-printed denture base resins. Resin discs were produced and randomly divided into groups: T0: no brushing; T1: simulated 1-year brushing; T2: simulated 2-year brushing. A soft-bristled toothbrush was used with one of the solutions: dentifrice (Colgate TOTAL®), disinfectant soap (Lifebuoy®), or distilled water (negative control group). Color stability, roughness and hardness (n = 9 each) tests were performed. Surface topography was analyzed by Scanning Electron Microscopy (n = 2). Data were analyzed using the Mann-Whitney U test (α = 5%). For comparison between the resins, the mean values and standard deviations of the variables for the types of resin and brushing times were obtained, controlling the solutions, using two-way ANOVA with Tukey's Post Hoc Test. For both resins, a statistically significant change in color stability was observed in the groups brushed with dentifrice after 2 years. There was an increased roughness in the samples brushed with the same solution. Concerning hardness, a decrease was observed regardless of the solution and the resin, after 2 years of brushing. Differences between resins were found in relation to color change and hardness. Both resins, heat-cured and 3D-printed, presented changes in color stability, increased roughness and decreased hardness after 2 years of brushing with dentifrice. Brushing with disinfectant soap caused the smallest changes in surface properties, which can be an option for brushing dentures.
