1 · What the graph read from it

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.

2 · The registry

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

BACKGROUND AND

objectivesHereditary hearing loss is the most common genetic disorder in children. Nearly 120 genes associated with auditory impairment have been identified. Although the disease is clinically and genetically complex, the chances of identifying deafness-causing loci increase when studying consanguineous families. Materials and.

methodsWhole-exome sequencing was performed to identify genetic variants underlying sensorineural hearing loss in affected individuals from a family with third-degree consanguineous practices.

resultsA homozygous deletion of 250.285 kb was identified in the 16p12.2 region encompassing three genes, METTL9, IGSF6, and OTOA, and a partial deletion of the NPIPB4 gene co-segregated within the family.

conclusionsThis study highlighted the genetic heterogeneity of hearing loss in consanguineous families. Future research should focus on the OTOA mutational spectrum in South Indian populations with hearing loss.
