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 and aim: Computer-aided design/computer-aided manufacturing (CAD/CAM)-fabricated space maintainers offer a reliable alternative to traditionally fabricated stainless steel (SST) appliances, avoiding their commonly encountered drawbacks. The aim of this study is to evaluate the shear peel bond strength of the CAD/CAM polyetheretherketone (PEEK) space maintainer in comparison with an SST one. Materials and methods: The study was conducted on 50 molars, divided into two groups: a customized PEEK band (study group) and a prefabricated SST orthodontic molar band (control group). The crowns of the study group were scanned using a lab scanner, the bands were designed using ExoCAD software, and the PEEK disks were milled. The inner surfaces of the PEEK bands were sandblasted, etched, rinsed, and dried. Both bands were cemented to the teeth using self-etch dual-cure resin cement. The sheer peel bond of the bands was tested twice, both before and after cementation, using an electromechanical tensile universal testing machine. The data were analyzed using Statistical Package for the Social Sciences (SPSS) software. Results: Prior to cementation, the peel bond strength of the PEEK band (0.02 ± 0.01) was significantly higher than the SST band (0.01 ± 0.00) ( Conclusion: PEEK bands designed with CAD/CAM technology showed a better shear peel bond than SST bands, both before and following cementation, which imply that PEEK might provide a dependable alternative for traditional SST bands used in pediatric dentistry.
