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
ImportantTrimming perforation margins is the basic procedure for any myringoplasties; however, to date, little literature has been reported on the effect of no trimming perforation margins on sandwich graft tympanoplasty.ObjectiveThe objective of this study was to compare the graft success rate, hearing improvement, and complications of endoscopic cartilage-perichondrium Sandwich technique (CPST) and cartilage-perichondrium underlay technique (CPUT) for repairing chronic large perforations.Study DesignProspective randomized controlled trial.SettingTertiary referral center.Participants and InterventionOne hundred two patients with chronic large perforations with 50% to 75% of tympanic membrane (TM) were recruited and randomly allocated to CPST (n = 51) and CPUT (n = 51), raising tympanomeatal flap and trimming perforation margins were not performed in both techniques.Main Outcome MeasurersThe graft success rate, air-bone gap (ABG) gain, operation time, and postoperative complications were evaluated at 12 months.ResultsAll the patients complete 12 months follow-up. The mean operation time was 30.6 ± 3.7 minutes in the CPST group and 29.8 ± 6.1 minutes in the CPUT group (
