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: Given the increasing prevalence of individuals using charcoal-based dentifrices over extended periods without professional oversight, concerns have emerged regarding their potential effects. This study aimed to investigate the influence of different charcoal-based products on color change (ΔE00), gloss stability, and surface roughness of dental enamel (Intact or bleached) and resin composites subjected to 12-month simulated brushing. Material and Methods: 132 bovine crowns were randomly allocated and restored with either SS-single-shade or conventional multi-shade, NH-nanohybrid, NF- nano-filled, or BF- bulk-fill composite. A conventional toothpaste (Control), a charcoal-based toothpaste (DC) , and a charcoal-based toothpowder (PO) were evaluated corresponding to 1-, 2-, 6-, and 12-month simulated tooth brushing, respectively. Color (ΔE00) and surface roughness (Ra) were assessed at baseline and after each brushing (n=11). Gloss (GU) was assessed before and after brushing. The brushing products, as well as the enamel and composite surfaces, were analyzed using scanning electron microscopy. Color change, gloss stability, and surface roughness were analyzed by a three-way repeated-measures analysis of variance followed by Tukey's test (α=0.05). Results: Significant differences were found for composite color change (ΔE00) based on brushing product ( Conclusions: Charcoal-based toothpaste alters the morphology, roughness, gloss, and color of enamel and resin composite, similar to regular toothpaste. Toothpowder creates surface irregularities, decreasing the gloss and increasing the color change and roughness, more strongly impacting bleached enamel and composites after 12-month simulated tooth brushing.
