Review in Nature reviews. Neurology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 26 papers, 1 of them a synthesis that pooled it.

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

Since the approval of riluzole for the treatment of amyotrophic lateral sclerosis (ALS) 17 years ago, more than 30 large clinical trials have been conducted, but none has proved successful. The failure to translate positive preclinical results into the clinical setting raises questions about the validity of the rodent model that is used to study ALS, and about the quality of both preclinical and clinical studies. However, the greatest challenge is the disease itself as, with rare exceptions, the causes are unknown. In this Perspectives article, we highlight key issues related to the pathophysiology, preclinical studies and clinical trials that should be addressed in the future. These areas include the relationships between different disease mechanisms, the challenges presented by the heterogeneity of the disease, and the need for early intervention, optimal dose selection and effective biomarkers.
