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

introductionPopeye domain containing 3 (

methodsThis is a case report from a neurology referral center in India. All the clinical, laboratory and electrophysiological data were collected from the medical records.

resultsA 34-year-old man born to non-consanguineous parents presented with progressive proximal weakness of lower limbs from 22 years of age. He developed calf muscle pain and recurrent falls on walking for 7 years. He had atrophy of calves (medial gastrocnemius more than lateral) along with weakness of hip extensor, adductors and knee flexors and normal upper limb power, resembling Miyoshi myopathy. Serum creatine kinase ranged from 3524 to 6531 U/L. Muscle MRI showed selective atrophy of gluteus maximus, quadriceps femoris, semimembranosus and gastrocnemius with sparing of rectus femoris, gracilis and sartorius. Muscle biopsy done elsewhere and reported to show dystrophic features and immunohistochemistry showed positive staining for dystrophins and sarcoglycans. Clinically the possibility of LGMDR2/Dysferlinopathy, was considered and whole exome sequencing was done which revealed a novel homozygous pathogenic nonsense premature termination codon (PTC) variant (NM_022361.5) c.316C > T (NP_079130.2:) p.Arg106Ter) in exon 2 of

conclusionThis is the first report of POPDC3- LGMDR26 from India detected among a large cohort (461 genetically confirmed cases).
