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
purposeTo evaluate the effects of titanium abutment surface treatment, screw access hole (SAH) filling method, and restoration internal surface treatment on the retention of CAD-CAM milled PMMA restorations. MATERIALS AND
methodsThe study was conducted in two phases. First, the effects of abutment airborne particle abrasion (APA) and SAH filling method (full, partial) on retention were evaluated (n = 19). Second, the effect of PMMA internal surface treatment (no treatment, MDP-containing primer, APA) was evaluated (n = 19). All specimens were cemented with a non-eugenol temporary cement. Thermomechanical aging was performed prior to pull-out test. Surface characteristics were analyzed using scanning electron microscope (SEM) and atomic force microscope (AFM). Statistical analysis included one-way and two-way ANOVA, Tukey's HSD test, multiple regression, and chi-square test (α = .05).
resultsAbutment APA significantly increased retention compared with untreated abutments (mean difference, 33.71 N; 95% CI, 21.34 to 46.08;
