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

In this study, we examined the potential causal effect of smoking on amyotrophic lateral sclerosis (ALS) using the Project MinE data involving 12,577 patients with ALS and 23,475 controls in a Mendelian randomization (MR) framework. The MR approach has the potential to investigate a causal relationship between a risk factor and a disease, avoiding confounding and information bias that often present in conventional epidemiological studies. We found that smokers had a higher risk of ALS compared to never smokers. Our study thus provides evidence for a causal relationship between smoking and ALS. Ann Neurol 2019;85:482-484.
