Characteristics of preoperative electrically evoked middle latency responses and postoperative cochlear implant effects in patients with tinnitus.
Article in Head & face medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo analyse the characteristics of electrically evoked middle latency responses (EMLR) in patients with profound sensorineural hearing loss (SNHL) and tinnitus.
methodsThirty adults with profound SNHL and tinnitus who underwent cochlear implantation were selected as the tinnitus group, and 15 patients with profound SNHL but without tinnitus served as the control group. Preoperative data were retrospectively analysed. Electrically evoked middle latency responses were recorded intraoperatively, and the electrophysiological characteristics were compared between groups. Changes in tinnitus were assessed using the Tinnitus Handicap Inventory (THI), and correlations between EMLR parameters and THI scores were analysed.
resultsNo postoperative complications occurred in any of the patients. Electroauditory responses were successfully elicited in all 45 patients. Intraoperative EMLR showed increased Na-Pa amplitude and delayed Pa latency, with significant differences observed between the tinnitus and control groups (P < 0.05). One year after cochlear implantation, the average comfort level (C value) and the EMLR threshold showed a significant linear correlation (r = 0.915, P < 0.01). Postoperative THI scores showed a significant decrease (P < 0.05) compared with preoperative scores. A significant correlation was found between the intraoperative EMLR Na-Pa wave amplitude and THI change at 1 year (r = 0.815, P < 0.05), with an area under the ROC curve of 0.673 (P = 0.002).
conclusionThe intraoperative EMLR waveform of patients with profound SNHL and tinnitus is significantly different from that of patients without tinnitus. Cochlear stimulation effectively inhibits tinnitus, and EMLR provides an objective tool for evaluating tinnitus and optimising its management. However, further studies with larger sample sizes are needed to validate these preliminary findings.
