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 treatment of digital ischemia remains difficult. Sildenafil (Viagra, Pfizer UK), a selective phosphodiesterase inhibitor, increases blood flow and is currently marketed for the treatment of erectile dysfunction. A case of a 57-year-old man with progressive episodic ischemia and pain of the fingertips resulting in finger tip ulceration is presented. After failure of medical and surgical management, a trial of oral sildenafil resulted in marked symptomatic improvement of his bilateral digital ischemia. Review of the literature shows that, particularly in patients with an underlying disease such as sclero-derma with a vasospastic component, a marked improvement in digital blood flow may be observed with sildenafil use. Overall, based on a number of case reports and preliminary animal studies in the literature, sildenafil appears to have a growing significance in the treatment of hand ischemia. Similarly, there is evidence that phosphodiesterase 5 inhibitors may be used as an adjunct to improving skin flap survival.
