Development of a Otologic Surgery Registry Using Hearing Threshold Data Linked to Medical Record Database in Japan: A Preliminary Study.
Article in Annals of clinical epidemiology, 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
backgroundRoutinely collected medical data, such as electronic medical records (EMRs) and medical claims, are necessary for developing disease registries. This study aimed to develop an otologic surgery registry by integrating data from EMRs, medical claims, and otorhinolaryngology department information systems (ORL-DIS) and to assess the agreement of hearing tests between registry-determined evaluations (RDE) and surgeon-determined evaluations (SDE).
methodsA stapes surgery registry was developed by linking data from ORL-DIS, EMRs, and medical claims from two hospitals in Japan. SDE were recorded by the surgeons, whereas RDE were automatically assigned by the registry system. This study focused on pre- and postoperative hearing evaluations. Pure-tone averages (PTA) for air conduction (AC) and bone conduction (BC) were calculated. Agreement between SDE and RDE was assessed using Bland-Altman plots, and mean differences and 95% limits of agreement (95% LoA) were calculated. In SDE, cases with incomplete data were excluded.
resultsA total of 164 patients (187 cases) were included. The Bland-Altman analysis revealed a high agreement between preoperative AC-PTA (mean difference: -1.61 dB; 95% LoA: -12.5 to 9.29 dB) and BC-PTA (mean difference: -1.05 dB; 95% LoA: -13.9 to 11.8 dB) measurements by SDE and RDE. Additionally, postoperative improvements showed a moderate agreement. The integration of audiometric data into the registry significantly reduced manual errors.
conclusionThis study successfully established the first otologic surgery registry in Japan that integrates audiometric data from EMRs. This registry provides a valuable resource for analyzing surgical outcomes and a framework for future otologic research.
