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

Amyotrophic lateral sclerosis (ALS) is a progressive disorder involving the degeneration of motor neurons. ALS shares pathogenic characteristics and genetic risk factors with multiple system atrophy (MSA). Here we examine whether a variant of the COQ2 gene associated with MSA in Japanese is also associated with ALS in Han Chinese. The ligase detection reaction was used to measure the frequency of the V393A variant of COQ2 in 282 patients with ALS and 491 healthy controls. The ALS and control groups showed no significant differences in genotype frequencies (OR 1.298, 95 %CI 0.396-4.253, p = 0.666) or allele frequencies (OR 1.314, 95 %CI 0.403-4.286, p = 0.650) at the V393A locus of COQ2. We also conducted a meta-analysis and combined our data with the previous Japanese research, but still failed to detect an association between V393A and ALS. In conclusion, This case-control study shows no evidence for an association between ALS and the V393A variant of COQ2 in Han Chinese and together with the Japanese research suggests that this polymorphism may not be linked to the risk of ALS in East Asians in general.
