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

The endothelium-derived vasoconstrictor molecule endothelin-1 (ET-1) has been suggested to play a role in the pathogenesis of Raynaud's phenomenon (RP) and systemic sclerosis (SSc). We studied the effect of bosentan on microvascular structure and function in patients with RP secondary to limited cutaneous SSc in a mechanistic pilot study. In this single center, open study, 15 patients with limited cutaneous SSc were treated with bosentan for 16 weeks with a follow-up period of 4 weeks. Changes in microvascular structure and function were studied with assessment of vasodilatory microvascular responses using laser Doppler fluxmetry combined with iontophoresis, capillary permeability using fluorescence videomicroscopy, nailfold capillary microscopy, and serological markers of endothelial activation. No significant changes were seen in vasodilator responses to acetylcholine and sodium nitroprusside following bosentan treatment. No effect was noted on capillary permeability during treatment. The number of nailfold capillaries remained unchanged. The endothelial activation marker vascular cell adhesion molecule did not change during treatment, but levels of thrombomodulin significantly decreased after 12 weeks of treatment. Bosentan did not induce significant changes in vasodilator responses, capillary permeability, and capillary density during treatment, so no evidence was obtained for structural improvement of microvascular structure and function in this short-time mechanistic pilot study in patients with lcSSc.
