Soluble guanylate cyclase beta1-subunit expression is increased in mononuclear cells from patients with erectile dysfunction.

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.
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 aim was to determine in circulating mononuclear cells from patients with erectile dysfunction (ED), the level of expression of endothelial nitric oxide synthase (eNOS), soluble guanylate cyclase (sGC) beta1-subunit and phosphodiesterase type-V (PDE-V). Peripheral mononuclear cells from nine patients with ED of vascular origin and nine patients with ED of neurological origin were obtained. Fourteen age-matched volunteers with normal erectile function were used as control. Reduction in eNOS protein was observed in the mononuclear cells from patients with ED of vascular origin but not in those from neurological origin. Although sGC beta1-subunit expression was increased in mononuclear cells from patients with ED, the sGC activity was reduced. However, only the patients with ED of vascular origin showed an increased expression of PDE-V. This work shows for the first time that, independently of the aetiology of ED, the expression of sGC beta1-subunit was increased in circulating mononuclear cells; however, the expression of both eNOS and PDE-V was only modified in the circulating mononuclear cells from patients with ED of vascular origin.
