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

Multiple sclerosis (MS) is an inflammatory demyelinating disease of the CNS caused by the interplay of genetic and environmental factors. In the last years, it has been suggested that an abnormal venous drainage due to stenosis or malformation of the internal jugular and/or azygous veins may play a major pathogenetic role in MS. This abnormality called chronic cerebro-spinal venous insufficiency (CCSVI) could result in increased permeability of blood brain barrier, local iron deposition and secondary multifocal inflammation. In the present paper, literature data in favour and against this hypothesis are reported. A great variability of CCSVI has been found in both MS patients (ranging from 0 to 100%) and in control subjects (from 0 to 23%). This large variability is explained by methodological aspects, problems in assessing CCSVI, and differences among clinical series. It is urgent to perform appropriate epidemiological studies to define the possible relationship between CCSVI and MS.
