Article in Scientific reports, 2025. 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
The current work investigates the effect of incorporating zinc oxide nanoparticles (ZnO NPs) into the polymer matrix polymethylmethacrylate (PMMA), focusing on structural, thermal, mechanical, and antimicrobial properties. The synthesized polymer nanocomposites, prepared via free radical emulsion polymerization, were characterized using Fourier Transform Infrared (FTIR) spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), thermal gravimetric analysis (TGA), and density measurements. Furthermore, the antibacterial and antimicrobial properties of the polymer nanocomposites were assessed against gram-negative bacteria (E. coli), gram-positive bacteria (S. mutans), and the fungus (C. albicans). Moreover, the mechanical characteristics, including Vickers micro-hardness, Young's modulus, tensile strength, and elongation at break, for pure PMMA and PMMA/ZnO nanocomposite films have also been examined. The results confirm that the structure of the host matrix changes slightly upon the addition of ZnO NPs. The density measurement shows an increase, and the thermal stability is enhanced by ~ 6% for an optimum concentration of ZnO NPs addition. Additionally, the hardness number reaches its maximum value with an increase of ~ 13.5%, which is a statistically significant difference. Moreover, mechanical properties (e.g., Young's modulus, tensile strength) and antibacterial and antimicrobial properties have shown remarkable changes. In conclusion, this work emphasizes optimal 3 wt% loading, attributed to the good dispersion of ZnO NPs, highlighting enhanced performance that can be used in denture-base applications.
