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 This in vitro study evaluated the effect of different surface treatments on the bond strength of polyetheretherketone (PEEK) and polyether-ketone-ketone (PEKK) polymers to resin cement. MATERIAL AND METHODS CAD/CAM-fabricated PEEK and PEKK specimens (7×7×2 mm) were divided into 8 groups (n=10 per group; total n=80), with 4 groups per material: control, argon plasma, sandblasting with 125-µm Al₂O₃, and sandblasting followed by argon plasma. Surface characteristics were analyzed using scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), and atomic force microscopy (AFM). All specimens were treated with a methyl methacrylate-based adhesive (Visio.link) and luted with resin cement (RelyX U200), then stored in air for 1 h. Shear bond strength was measured using a universal testing machine. Data were analyzed using Kolmogorov-Smirnov, Levene, one-way ANOVA, Bonferroni, and independent t tests (alpha=0.05). RESULTS Surface treatment significantly affected bond strength (P<0.05). The highest bond strengths for both polymers were achieved with sandblasting followed by argon plasma treatment. Although PEKK showed slightly higher bond strengths than PEEK, the difference was not statistically significant (P>0.05). The lowest bond strengths were observed in the control groups (PEEK: 7.1±0.6 MPa; PEKK: 7.6±1.2 MPa), while the highest values were recorded after combined sandblasting and argon plasma treatment (PEEK: 12.2±2.4 MPa; PEKK: 12.6±2.4 MPa). CONCLUSIONS Surface treatment significantly influences the bond strength of PEEK and PEKK to resin cement. Argon plasma application after sandblasting markedly enhanced shear bond strength for both materials.
