Validating a New Tablet-based Tool in the Determination of Cochlear Implant Angular Insertion Depth.
Article in Otology & neurotology : official publication of the American Otological Society, American Neurotology Society [and] European Academy of Otology and Neurotology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 31 papers.
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
objectiveThe objective of this study is to determine the reliability of a new tablet-based software that utilizes postoperative computed tomography to determine angular insertion depth (AID), cochlear duct length (CDL), and the cochlear place frequency of individual electrodes in cochlear implant recipients. PATIENTS: Twenty adult cochlear implant recipients with lateral-wall electrode arrays of varying lengths were included in the study.
interventionCochlear and electrode array measurements were made by 2 otolaryngologists using a tablet-based software. The user manually identifies the modiolus, round window, and each electrode contact to calculate AID. The user also manually identifies cochlear landmarks to calculate the CDL. The AID and CDL are applied to the Greenwood function to obtain an estimate of the cochlear place frequency for each electrode. MAIN OUTCOME MEASURE(S): The primary outcome measure was the reliability of the instrument, as assessed with intra and interrater reliability of measured AID and CDL. The resultant differences in the estimated cochlear place frequency of the most apical electrode were also evaluated.
resultsA broad range of AIDs were observed (390°-659°). Intraclass correlation coefficients for intra (0.991) and interrater reliability (0.980) of AID of the most apical electrode contact were excellent. Intra (0.820) and interrater reliability (0.784) of CDL were also excellent. The estimated cochlear place frequency for the most apical electrode differed by an average of 6.7% (0-18.7%) across the 2 raters.
conclusionThere is excellent agreement amongst clinicians in the determination of AID and CDL, resulting in small changes in estimated cochlear place frequency of the most apical electrode using this new software.
