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

Erectile dysfunction (ED) is usually treated with sildenafil. Although genetic polymorphisms in the endothelial nitric oxide synthase (eNOS) gene may impair endogenous NO formation, there is little information about how eNOS polymorphisms and haplotypes affect the responses to sildenafil. We studied 118 patients; 63 patients had ED secondary to radical prostatectomy (PED) and 55 had organic, clinical ED. eNOS genotypes for three eNOS polymorphisms (T(-786)C, rs2070744; a variable number of tandem repeats (VNTR) in intron 4; and Glu298Asp, rs1799983) were determined, and eNOS haplotypes were estimated using PHASE 2.1. The clinical responses to sildenafil were evaluated and the patients were classified as good responders (GR) or poor responders (PR) when their changes in five-item version of International Index for Erectile Function questionnaire were above or below the median value. The TC/CC genotypes and the C allele for the T(-786)C polymorphism were more common in GR, compared with PR patients with PED. However, the 4b4a/4a4a genotypes and the 4a allele for the VNTR polymorphism in intron 4 were more common in GR, compared with PR patients with clinical ED. The C-4a-Glu haplotype was more common in GR than in PR patients with PED. Conversely, the T-4b-Asp haplotype was less common in GR than in PR patients with PED. No other significant differences were found. Our findings show evidence that eNOS polymorphisms affect the responses of PED and clinical ED patients to sildenafil.
