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

West syndrome, which is narrowly defined as infantile spasms that occur in clusters and hypsarrhythmia on EEG, is the most common early-onset epileptic encephalopathy (EOEE). Patients with West syndrome may have clear etiologies, including perinatal events, infections, gross chromosomal abnormalities, or cases followed by other EOEEs. However, the genetic etiology of most cases of West syndrome remains unexplained. DNA from 18 patients with unexplained West syndrome was subjected to microarray-based comparative genomic hybridization (array CGH), followed by trio-based whole-exome sequencing in 14 unsolved families. We identified candidate pathogenic variants in 50% of the patients (n = 9/18). The array CGH revealed candidate pathogenic copy number variations in four cases (22%, 4/18), including an Xq28 duplication, a 16p11.2 deletion, a 16p13.1 deletion and a 19p13.2 deletion disrupting CACNA1A. Whole-exome sequencing identified candidate mutations in known epilepsy genes in five cases (36%, 5/14). Three candidate de novo mutations were identified in three cases, with two mutations occurring in two new candidate genes (NR2F1 and CACNA2D1) (21%, 3/14). Hemizygous candidate mutations in ALG13 and BRWD3 were identified in the other two cases (14%, 2/14). Evaluating a panel of 67 known EOEE genes failed to identify significant mutations. Despite the heterogeneity of unexplained West syndrome, the combination of array CGH and whole-exome sequencing is an effective means of evaluating the genetic background in unexplained West syndrome. We provide additional evidence for NR2F1 as a causative gene and for CACNA2D1 and BRWD3 as candidate genes for West syndrome.
