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

objectivesXenotropic murine leukemia virus-related virus (XMRV)-specific proviral DNA has been recently detected in peripheral blood mononuclear cells of patients with chronic fatigue syndrome. Since chronic fatigue is commonly reported in patients with systemic lupus erythematosus (SLE) we aimed at testing the presence of this virus in these patients.

methodsNinety-five SLE patients, 45 of whom had a Fatigue Severity Scale score higher than 3, were included. Molecular analyses were performed by PCR from DNA obtained from the whole blood of both SLE patients and 50 healthy controls.

resultsNone of the 145 samples analyzed yielded the specific XMRV PCR product.

conclusionsWe conclude that XMRV is not detected in blood neither from SLE patients nor from healthy controls. It leads to infer that other environmental and biological triggers (different from XMRV) may account for the increased levels of fatigue over the course of SLE.
