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: To compare the indications and efficacy of endoscopic over-under tympanoplasty versus endoscopic underlay tympanoplasty. Methods: Retrospective cohort study of patients undergoing type I endoscopic tympanoplasty via either an underlay or over-under technique by a single surgeon from 2017 to 2021. Patients were excluded if they had a concurrent mastoidectomy, ossiculoplasty, or advanced cholesteatoma defined by involvement of multiple subsites. Patient demographics, perforation size and location, middle ear status, preoperative and postoperative audiograms, and perforation closure were reviewed. Middle ear status was represented using the Ossiculoplasty Outcome Parameter Score (OOPS). The primary outcome was perforation closure at most recent follow-up and secondary outcomes were change in postoperative pure-tone average (PTA) and air-bone gap (ABG). Results: Of 48 patients, 27 underwent endoscopic underlay tympanoplasty and 21 underwent endoscopic over-under tympanoplasty. Tragal cartilage-perichondrium graft was used in 90% of procedures. Distribution of OOPS scores was not significantly different between groups. Over- under technique addressed significantly larger perforations (mean size of 54% vs. 31%, Conclusion: The endoscopic over-under tympanoplasty is comparable to endoscopic underlay tympanoplasty in terms of graft take and audiologic improvement. The over-under technique is effective for repairing larger perforations or those with anterior extension. Level of evidence: IV.
