Multivariate analysis of the effect of staining beverages on the optical properties of two provisional restorative materials.
Article in Journal of clinical and experimental dentistry, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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: To evaluate the effect of staining beverages on the color stability, translucency and gloss of two provisional restorative materials. Material and Methods: Sixty discs (8 mm x 2 mm) were manufactured for Duralay and Protemp 4. The discs were randomly divided according to the beverages: tea, coffee, wine, Coca-Cola and "Chicha morada" (n=12). The discs were polished and initial recordings of color and translucency were made with a spectrophotometer, and the gloss was measured with a glossmeter. The discs were immersed for 5 days in each of the beverages at 37◦C, and the color, translucency and gloss were recorded again. The differences between the initial and final records were calculated to obtain the values of ΔE, ΔTP, ΔGU. For the analysis, the two-way MANOVA model was chosen, and the significance level was set at 5%. Results: A significant interaction was observed between the type of material and the staining beverages on the changes observed in the values of ΔE, ΔTP, ΔGU ( Conclusions: The type of material and the pigment drinks act together to influence changes in color, translucency and gloss. The methacrylate-based resin was more stable than the bis-acrylic resin to changes in color, translucency and gloss.
