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

purposeAn increasing number of cochlear implant (CI) users is examined by magnetic resonance imaging which may cause the displacement of the implant magnet. This complication prevents the usage of the external processor and has to be treated surgically in most cases. The purpose of this study is to analyze the results of the surgical intervention and the consequences for the CI recipients.

methodsThe retrospective study was conducted at a tertiary referral center. From the patient care records between October 2014 and July 2018, 9 cases were reviewed that had undergone MRI after cochlear implantation and had experienced magnet displacement.

resultsNine patients from 9 to 74 years of age were identified with MRI-induced magnet displacement. Implants of different manufacturers were affected (8 × Cochlear

conclusionsThe present study shows that in the majority of cases a surgical magnet reposition is possible without complications, and thus the time of nonuse of the CI is usually low. Nevertheless, there is a risk that in individual cases significant medical, functional, social and economic consequences for patients may occur. The presented data demonstrate that the indication to perform MRI scans in CI users needs to be further critically considered. An attentive, critical assessment of an MRI indication by both the initiating physician (usually not an ENT specialist) and the performing radiologist is mandatory.
