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
Objectives: To find out influence of advanced surface modification techniques (argon (Ar) Plasma, Femtosecond (FS) laser, and nano-hydroxyapatite (HA) coating) on the surface roughness (Ra) and shear bond strength (SBS) of resin luting cement to polyetheretherketone (PEEK). Methods: The lab-based comparative study followed a checklist for reporting in vitro study (CRIS) guidelines. The study was completed in two months (January 10, 2025, to March 10, 2025) at King Saud University. The study was conducted on sixty-four CAD CAM Vestakeep PEEK tooth-colored discs, divided into four groups (n=16) based on different conditioning methods SA (Group-1), Ar Plasma (Group-2), FS laser (Group-3), and nano-HA coating (Group-4). The Ra was evaluated using a profilometer, while topographical assessments were performed using scanning electron microscopy. Forty samples were subjected to resin cement luting, followed by artificial aging. A universal testing machine was utilized for SBS testing, and failure mode determination was performed using a stereomicroscope. Statistical analysis involved a one-way analysis of variance and Tukey's Post Hoc test, with significance set at p=0.05. Results: The highest Ra (1299.53 ± 0.015) and SBS (15.13 ± 0.11 MPa) values were observed in Group-3 (FS laser). Conversely, the lowest Ra (888.58±0.011) and bond strength (13.43±0.09 MPa) values were exhibited by Group-4 (Nano-HA coatings) specimens. Conclusion: The application of Argon Plasma and Femtosecond laser techniques has shown promise as viable alternatives for PEEK surface conditioning.
