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

objectiveThis work aims to expand knowledge regarding the genetic spectrum of HSPB1-related diseases. HSPB1 is a gene encoding heat shock protein 27, and mutations in HSPB1 have been identified as the cause of axonal Charcot-Marie-Tooth (CMT) disease type 2F and distal hereditary motor neuropathy (dHMN).

methodsTwo patients with axonal sensorimotor neuropathy underwent detailed clinical examinations, neurophysiological studies, and next-generation sequencing with subsequent bioinformatic prioritization of genetic variants and in silico analysis of the likely causal mutation.

resultsThe HSPB1 p.S135F and p.R136L mutations were identified in homozygosis in the two affected individuals. Both mutations affect the highly conserved alpha-crystallin domain and have been previously described as the cause of severe CMT2F/dHMN, showing a strictly dominant inheritance pattern.

interpretationThus, we report for the first time two cases of biallelic HSPB1 p.S135F and p.R136L mutations in two families.
