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

objectiveThe aim of this study was to investigate the effects of 3 Tesla (3T) magnetic resonance imaging (MRI) noise on cochlear functions.

methodsThe distortion product otoacoustic emission (DPOAE) test was applied to patients who were scheduled to have 3T MRI in the tertiary care center. Patients who revealed emission amplitudes at all frequencies (1, 1.5, 2, 3, 4, 6, and 8 kHz) in the DPOAE test before MRI were included in the study. After MRI, the DPOAE test was performed twice on 17 patients (33 ears) (immediately after MRI and 30 minutes after MRI). The changes in the results of the tests taken before MRI (pre-MRI), immediately after MRI (post-MRI 1), and at 30 minutes after MRI (post-MRI 2) in the DPOAE amplitudes at all frequencies were compared statistically.

resultsThere was a significant difference between pre-MRI, post-MRI 1, and post-MRI 2 measurements at 3, 6, and 8 kHz. In pairwise comparisons; post-MRI 1 was statistically lower than post-MRI 2 at 3 kHz, and post-MRI 1 was statistically lower than pre-MRI and post-MRI 2 at 6 and 8 kHz. In addition, post-MRI 2 was significantly lower than pre-MRI at 8 kHz.

conclusionAccording to these results, 3T MRI noise does not have any permanent negative impact on hearing functions. It can only cause DPOAE amplitude changes at high frequencies. This is a clinically negligible effect. Therefore, it can be considered that the 3T MRI examination with protective headphones does not cause any adverse side effects in terms of hearing functions.
