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

backgroundMonilethrix is a rare hereditary hair loss disorder characterized by hair fragility and beaded hair shaft alterations. Monilethrix is classically inherited in an autosomal dominant (AD) fashion caused by variants in the hair keratin genes KRT81, KRT83, or KRT86. Interestingly, an autosomal recessive (AR) form of monilethrix with variants in DSG4 gene has also been reported in recent years.

objectiveTo identify causative variants in Chinese patients with autosomal recessive (AR) form of monilethrix.

methodsThree families with AR form of monilethrix were observed and sequence variant analysis of DSG4 was performed by polymerase chain reaction (PCR), quantitative real-time PCR, and DNA sequencing.

resultsAll the patients had sparse, fragile hair involving the scalp, eyebrows, and eyelashes with keratotic follicular papules and pruritus since birth. Atypical-beaded hairs and broken hair shaft fragments were identified in all the patients under dermoscopy. Heterozygous variants c.837del and c. 2389C > T, a homozygous splice site variant c.2355 + 1G > A, and a homozygous 48,644 bp large deletion variant g.31381440_31430084del in the DSG4 gene were identified and verified in the families.

conclusionThis report provided further evidence for the phenotypic spectrum and clinical features of, and the expanded variant database of AR form of monilethrix.
