Screening for Hearing Impairment in Newborns Using Targeted Genomic Sequencing: A Large Pilot Cohort Study.

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
objectivesState-run newborn hearing screening (NBHS) programs have limitations in identifying children with mild or late-onset sensorineural hearing impairment (SNHI). Given that over 50% of pediatric SNHI cases are linked to genetic causes, the increasing accessibility of high-throughput, low-cost genomic sequencing may help address these shortcomings. This study investigates the feasibility of integrating a next-generation sequencing (NGS)-based genomic screening protocol into conventional NBHS and examines its potential benefits and challenges.
methodsA total of 8,261 newborns underwent simultaneous NBHS and NGS-based genomic screening targeting 46 deafness genes in this prospective study. The subjects' genotypes were determined, and those with conclusive genetic diagnoses received audiological assessments.
resultsConclusive genetic diagnoses were confirmed in 164 subjects, with 112 carrying variants in GJB2 and MTRNR1 and 52 carrying variants in other deafness genes. Notably, 126 of these subjects passed the NBHS, suggesting that an additional 1.5% (126/8,261) of children at risk for SNHI, who would have been missed by conventional physiological screening, can be identified through targeted genomic screening in the general population. Furthermore, one subject's father, who carried a COL4A5 variant, and three paternal relatives of another subject carrying an EDNRB variant (previously undiagnosed) were identified with Alport and Waardenburg syndromes, respectively, underscoring the familial benefits of this approach.
conclusionTargeted genomic sequencing in newborns may serve as a valuable complement to conventional NBHS by identifying children at risk for SNHI and enabling early diagnosis in families with non-syndromic mimics.
