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: This study aims to assess the impact of various surface roughening treatments and bonding agents on aesthetic crown materials for the bonding of clear aligner attachments in orthodontic treatment. The primary objective is to assess their impact on shear bond strength, and the secondary objective is to assess their effect on surface roughness. Methods: This systematic review of literature (2015-2025) followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Data were collected from scientific articles investigating the impact of various surface roughening procedures on the bond strength and surface roughness for clear aligner attachments bonded to aesthetic crown materials. The articles were retrieved from three databases: Scopus, PubMed, and Web of Science. Risk of bias was assessed using the QUIN bias assessment tool for dental Results: The results of the included articles were organised into tables in Word under the headings of author, country, material used, intervention(s), and results. The findings showed a positive increase in bond strength and surface roughness following surface treatments. Conclusion: This systematic review concludes that etching with hydrofluoric acid for 1 min and bonding with Filtek Z350 composite resin result in relatively higher bond strength and surface roughness. These findings may assist orthodontists in enhancing the bond strength of clear aligner attachments to aesthetic crown materials, hence improving orthodontic tooth movement.
