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

purposeThe aim of this study was to analyze the surgical outcomes of endoscopic tympanoplasty (ET) type I, and to investigate the learning curve of ET type I in a surgeon experienced in microscopic surgery.

methodsWe retrospectively studied patients with tympanic membrane perforations who had undergone ET type I from January 2015 to June 2020. All procedures were performed by a single senior surgeon with considerable microscopic experience. We compared the perforation closure rate in relation to age, previous ear surgery history, graft material, size, and location of perforation. We compared the operation time according to the number of operated patients.

resultsA total of 399 patients were enrolled. The success rate of ET type I was 92.7%. Age, prior ear surgery, graft material, size, and location of perforation did not influence the surgical outcomes. The surgical time for the initial ten cases was the longest (78.3 min), and stabilized after the first 100 cases to under 60 min. The surgical success rate was 96.0% in the first 50 cases, and decreased to approximately 92% afterwards.

conclusionThe surgical time largely decreased with the number of operated patients. Since the operations were performed by a surgeon experienced in microscopy, the success rate of initial cases was not low, even though the operation time of these initial cases was longer. We believe that endoscope provides a new perspective on ear surgery if it could overcome the difficulties in the early stage.
