High prevalence of syndromic hearing loss in Mexican children undergoing cochlear implantation.
Article in Laryngoscope investigative otolaryngology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Objective: Studies evaluating genetic sensorineural hearing loss (SNHL) in Hispanic and Latino populations using genomic technologies are lacking. Recent data has shown that Hispanic and Latino children display lower genetic diagnostic rates despite similar prevalence rates of SNHL to their Asian and White counterparts, thus negatively affecting their clinical care. Our objective was to determine the genetic contribution to SNHL in a population of Mexican children undergoing evaluation for cochlear implantation. Methods: Pediatric patients from Mexico with severe to profound SNHL undergoing evaluation for cochlear implantation were recruited. Exome sequencing (ES) or hearing loss gene panel testing was performed. Variant pathogenicity was established in accordance to criteria established by the American College of Medical Genetics, and variants of interest were clinically confirmed via CLIA certified laboratory. Results: Genetic evaluation was completed for 30 Mexican children with severe to profound SNHL. A genetic cause was identified for 47% (14) of probands, and 7% (2) probands had an inconclusive result. Of the diagnoses, 10 (71%) were syndromic or likely syndromic, and 4 (29%) were nonsyndromic. Eight probands (80% of all syndromic diagnoses) were diagnosed with a syndromic form of hearing loss that mimics a nonsyndromic clinical presentation at a young age and so could not be suspected based on clinical evaluation alone without genetic testing. Conclusion: This is the largest study to date to use comprehensive genomic testing for the evaluation of Mexican children with severe to profound SNHL. A significant proportion of children in this cohort were diagnosed with syndromic hearing loss. Future study in a larger cohort of Mexican children with varying degrees of hearing loss is required to improve the efficacy of genetic testing and timely medical intervention within these ethnically diverse populations. Level of evidence: Level 4 (cohort study).
