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

Arginase 1 (ARG1) and arginase 2 (ARG2) compete with nitric oxide synthases for the substrate l-arginine. Here we aim to assess whether arginase 1 and 2 plasma levels, plasma arginase activity or genetic factors are associated with altered responsiveness to sildenafil. We studied 71 post-prostatectomy erectile dysfunction (ED) patients (PED group) and 72 clinical ED patients (CED). Patients responded to the International Index of Erectile Function questionnaire before and after the treatment. We found positive and negative correlations between plasma levels of arginase 1 and sildenafil responsiveness in the PED and CED groups, respectively. PED group also presented negative correlation between plasma arginase activity and sildenafil responsiveness. Sildenafil poor responders have shown higher plasma arginase activity in PED and higher arginase 1 levels on CED groups. In addition, variant genotypes for the rs2781659, rs2781667 and rs17599586 polymorphisms were associated with reduced arginase activity, as well as the GTTT ARG1 haplotype in CED group.
