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

Introduction: Rapidly progressive para- or tetraparesis and early loss of F-waves on electrodiagnostic studies usually indicate acute inflammatory demyelinating polyneuropathy. A less common alternative etiology is acute spinal cord pathology. Case Presentation: We describe here a case of a 65-year-old woman with progressive motor deficits and absent F-waves early in the disease course due to anterior spinal artery syndrome. We provide serial electrodiagnostic findings with a focus on the basic electrodiagnostic parameters as well as imaging correlates during the inpatient management. Conclusion: Anterior spinal artery syndrome represents an uncommon cause of absent F-waves on the electrodiagnostic exam. Absent F-waves may precede any changes on the imaging and follow-up investigations are often warranted, as spinal cord ischemia can be a dynamic process.
