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

Capillary malformation-arteriovenous type 2 syndrome (CM-AVM2) is a rare, genetic vascular disorder associated with abnormal capillary malformations and arteriovenous malformations. We present a case of CM-AVM2 with refractory diarrhea and failure to thrive due to aberrant, telangiectatic capillaries, and subepithelial collagen deposition found throughout the GI tract on bidirectional endoscopy. The patient was recalcitrant to standard therapies, so bevacizumab was trialed, but the patient expired. This is the first case of CM-AVM2 with diffuse GI mucosal involvement resulting in malabsorption. There is no treatment for this pathology, but treatment with bevacizumab or a mammalian target of rapamycin inhibitor may be efficacious.
