1 · What the graph read from it

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.

2 · The registry

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

Objective: We aimed to compare the graft success rate and hearing outcomes in patients with large tympanic membrane (TM) perforation in underlay and over-underlay approaches. Methods: This is a prospective double-blind randomized controlled clinical trial with a parallel design. Patients aged 15-75 years old with large TM perforation (more than 50% of TM) who operated at Khalili hospital affiliated with Shiraz University of Medical Science, Iran, were enrolled. Exclusion criteria were recent otorrhea, revision surgery, and pathologic intraoperative findings such as the presence of cholesteatoma, cholesterol granuloma, ear canal polyp, or damaged ossicle. In the first group, the underlay method and in the second group over-underlay method were performed. Graft success rate, atelectasis, and audiology outcomes were evaluated after 6 months. Results: The investigation was conducted on 84 patients in the underlay and 67 patients in the over-underlay group. Although there was a higher rate of graft failure (9%) in the over-underlay group in comparison with the underlay group (4.8%), the difference was not statistically significant ( Conclusion: Both techniques provide the same graft success rate, but SRT and ABG were significantly lower in the over-underlay technique after the operation. Levels of Evidence: 1b.
