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

Excitation-contraction (EC) coupling is an essential process for skeletal muscle function. Pathogenic variants in different EC coupling components have previously been associated with various neuromuscular disorders. In this study we aimed to identify the genetic etiology of a muscular condition characterized by early-onset muscle weakness, elevated CK, ptosis and low body weight, which was observed in three individuals from two unrelated consanguineous families. Exome sequencing (ES) performed in multiple individuals of one family, and ES in combination with SNP array-based homozygosity mapping in the proband of the other family, revealed different homozygous loss-of-function variants in the second exon of CACNB1 in the affected individuals from each family. CACNB1 encodes the β1 subunit of the skeletal muscle dihydropyridine receptor (DHPR), a voltage-gated Ca
