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

objectiveTo compare the potential beneficial effects of the angiotensin converting enzyme inhibitor (ACEI) benazepril and the angiotensin II receptor 1 blocker (ARB) irbesartan on vaginal vascular remodeling and fibrosis in female spontaneously hypertensive rats (SHRs).

methodsTwelve-week-old female SHRs were treated with irbesartan or benazepril for 12 weeks. Vaginal renin angiotensin system (RAS) components were detected by polymerase chain reaction and western blot and vaginal α-smooth muscle actin (α-SMA), endothelial nitric oxide synthase (eNOS), and collagen III (Col III) were analyzed by western blot. Vaginal tissue sections were examined by hematoxylin and eosin staining, Masson trichrome staining, and immunohistochemical analysis of α-SMA and Col III.

resultsIrbesartan and benazepril had different impacts on vaginal RAS components. Both agents decreased vaginal α-SMA and Col III and increased eNOS expression in SHR. The wall/lumen thickness ratio of vaginal arterioles was similarly decreased following irbesartan and benazepril treatment. Both drugs also decreased collagen deposition in SHRs. There was no difference in vaginal vascular remodeling or fibrosis between the two groups.

conclusionsIrbesartan and benazepril have different effects on vaginal RAS expression but similar positive effects against vaginal vascular remodeling and fibrosis.
