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

purposeThe antihypertensive effect of angiotensin-converting enzyme inhibitors (ACEi) is attributed partially to increased nitric oxide bioavailability. It is possible that functional polymorphisms in endothelial nitric oxide synthase (eNOS) and bradykinin receptor B2 (BDKRB2) genes may affect the antihypertensive response to enalapril.

methodsWe evaluated 106 hypertensive patients treated only with enalapril for 60 days. The difference between the mean arterial pressure (MAP) before and after the antihypertensive treatment was defined as ΔMAP. If ΔMAP were below or above the median value, the patients were classified as poor responders (PR) or good responders (GR), respectively. eNOS genotypes for the T(-786)C, G894T and 4b/4a polymorphisms were determined and haplotype frequencies were estimated by PHASE and Haplo.stats programs. The C(-58)T and BE1 +9/-9 polymorphisms of BDKRB2 genes and their haplotypes were determined by DNA sequencing. Robust multifactor dimensionality reduction analysis was used to characterize gene-gene interactions.

resultsThe TC/CC genotypes and the C allele for the eNOS T(-786)C polymorphism were more frequent in GR than in PR. Furthermore, the TT genotype for the BDKRB2 C(-58)T polymorphism was more frequent in PR than GR. No other significant differences in genotypes or haplotypes were found. However, we found significant gene-gene interactions: the CC genotype for the BDKRB2 C(-58)T polymorphism was associated with response to enalapril depending on eNOS T(-786)C genotypes.

conclusionsThese findings suggest that eNOS T(-786)C and BDKRB2 C(-58)T polymorphisms may synergically affect the antihypertensive response to enalapril.
