Surface hardness and roughness in glass fiber-modified polymethyl methacrylate resin: An
Article in Bioinformation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Conventional polymethyl methacrylate denture base resin exhibits inadequate surface hardness and increased surface roughness, affecting durability and promoting microbial colonization. Therefore, it is of interest to evaluate the effect of different glass fiber forms on surface hardness and roughness of heat-cured polymethyl methacrylate. Hence, eighty specimens were divided into four groups (n=20): control, woven fiber, chopped fiber and longitudinal fiber reinforcement (2.5 wt %) and tested using Vickers microhardness and profilometry. Longitudinal fiber reinforcement showed the highest surface hardness (20.99 ± 0.28 VHN), while woven fibers produced significantly greater surface roughness compared to control (p < 0.001). Thus, we show that glass fiber reinforcement improves hardness but increases roughness, with longitudinal fibers providing the most favorable balance for clinical application.
