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
purposeThe purpose of this study was to assess the effect of Ga-Al-Ar diode, Nd:YAG lasers, and chemical disinfectants (NaOCl, vinegar, and Corega) on surface roughness (Ra) and hardness (VHN) of polymethylmethacrylate (PMMA), thermoplastic polyamide, milled and 3D-printed denture base resins. MATERIALS AND
methodsAbout 432 specimens of PMMA, thermoplastic polyamide, milled, and 3D-printed resins were divided into six subgroups (n = 18): distilled water (control:C), Ga-Al-Ar diode laser (L1), Nd:YAG laser (L2), 1% sodium hypochlorite (NaOCl), vinegar (AA), and Corega (CR). Each specimen's Ra and VHN were measured. Surface topography assessment was done using scanning electron microscopy (SEM). Analysis was done using ANOVA and post hoc Tukey's test (p = 0.05).
resultsA significant difference was noted in Ra and VHN as affected by denture base materials, surface disinfectants, and their interaction (p < 0.001). Results showed a significant increase in Ra of PMMA with NaOCL (p < 0.001), AA (p = 0.005), and CR (p = 0.009), thermoplastic polyamide with L1 (p = 0.012), L2 (p = 0.015), NaOCL AA, and CR (p < 0.001 each), milled resin with AA NaOCL, and CR (p < 0.001 each), and 3D-printed resin with L1, NaOCl, AA (p < 0.001 each), and CR (p = 0.008). The VHN increased in PMMA with NaOCL (p < 0.001), AA (p = 0.044), and CR (p < 0.001), thermoplastic polyamide with L1 (p = 0.037), milled resin with L1, L2, and CR (p < 0.001 each), and 3D-printed resin with L1, NaOCl (p < 0.001 each), and decreased with CR (p = 0.007).
conclusionThe tested properties showed variations affected by denture base material and surface disinfectants. Laser treatments induced smoother surfaces than chemical disinfectants. Laser improved the surface hardness of CAD-CAM resins, while chemical immersion improved that of PMMA.
