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
Mutations in the genes, GJB2 and GJB6 play an important role in autosomal recessive, non-syndromic hearing loss. This study is aimed to detect the association of mutations in GJB2 and GJB6 genes in familial autosomal recessive non-syndromic hearing impairment cases. We included 26 families with at least two affected individuals having congenital bilateral, non-syndromic sensorineural hearing loss. Blood samples were drawn, DNA was extracted, and sent for multiplex PCR and Sanger sequencing. Of the 26 families analyzed, GJB2 mutations were detected in 9(34.6%) and GJB6 mutations were not detected in any of the families. GJB2 mutations are a major cause of congenital, non-syndromic hearing loss in this study population. This study also suggests that GJB6 mutations do not contribute to autosomal recessive non-syndromic hearing loss in the Indian population.
