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
purposeThe Vibrant Soundbridge active middle ear implant is indicated for the treatment of different types of hearing loss. Recently, a novel system for determining implant performance based on auditory brainstem response (ABR) was developed. A reference value for the expected ABR hearing thresholds is determined on the base of a substantial number of measurements in this work.
methodABRs were recorded in patients following VSB surgery. A standard ABR system was employed, utilizing an implemented optimized chirp stimulus, which was transmitted directly to the VSB via the AcoustiAP transmission unit (MED-EL). The study included 104 subjects with different types of hearing loss. Six distinct VSB couplers were utilized in this cohort.
resultsABR were recorded in all patients. The intraoperative ABR thresholds were 20.1 dB higher compared to the preoperative BC thresholds, 15.9 dB higher compared to the postoperative vibrogram, and 13.4 dB higher compared with the vibrogram thresholds determined at the first fitting. No significant differences were observed between the different couplers in either the investigated methods.
conclusionIt can be posited that the presented intraoperative measurement reference value enhances the interpretability of ABR in VSB and should be considered, when using this method in VSB surgery.
