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
backgroundThe aim of this study is to evaluate the indications and efficacy of facial nerve decompression through an endoscopic transcanal approach for patients with traumatic facial paralysis.
methodsThis single-center retrospective study included 11 patients with traumatic facial paralysis from February 2018 to April 2019. We compared the facial nerve and auditory function before and after operation so as to reveal the feasibility and effect of the surgical approach.
resultsAll 11 patients have successfully received facial nerve decompression through endoscopic transcanal approach. Facial nerve function was objectively evaluated by electroneurography test and House-Brackmann facial nerve grading system. All patients were graded HB-VI with electroneurography ≥ 95% before surgery. The recovery of facial nerve function was good (HB-I or II) (90.9%) a year after surgery with only one case (9.1%) for HB-III. Preoperative high-resolution computed tomography showed that 1 patient had ossicular chain interruption, which was confirmed during operation. Meanwhile, 2 patients with air-bone gap >35 dBHL and whose computed tomography failed to diagnose were found with ossicular chain interruption during operation. The air-bone gap of patients with normal ossicular chain connection was all <30 dBHL. The average air-bone gap was reduced from 27.5 ± 10.1 dBHL to 7.8 ± 3.3 dBHL after operation.
conclusionPreoperative high-resolution computed tomography combined with localization test can accurately estimate the location of facial nerve injury. Facial nerve decompression through endoscopic transcanal approach can decompress the geniculate ganglion to pyramidal segment of facial nerve, which is suitable for patients with traumatic facial paralysis of this segment. In addition, air-bone gap >35 dBHL may indicate the ossicular chain interruption when it is difficult to be completely judged by high-resolution computed tomography.
