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

Endothelin-1 is elevated in women with polycystic ovary syndrome (PCOS), and may play a role in the endothelial dysfunction associated with PCOS. Endothelin-1 binds two receptor subtypes, endothelin A (ET-A) and endothelin B (ET-B). We hypothesized that ET-A mediates vasoconstriction in the cutaneous microvasculature in women with and without PCOS. We further hypothesized that while the ET-B receptors mediate vasodilatation in both groups of women, this response would be blunted in women with PCOS. During local skin warming, we used laser Doppler flowmetry combined with intradermal microdialysis to measure skin blood flow (SkBF) during graded ET-A (BQ-123) and ET-B (BQ-788) antagonist infusions in women with (n = 6) and without (n = 8) PCOS. In both groups, SkBF increased during local heating. The percentage of maximal SkBF-[BQ123] sigmoidal dose-response curve indicated a vasodilatory response as the concentration of the antagonist increased (Hill slope 4.96 ± 4.77, 4.74 ± 5.01; logED(50) 2.53 ± 0.09, 2.49 ± 0.09 nm, for PCOS and Control, respectively). In contrast, the % max SkBF-[BQ788] curve indicated a vasoconstrictive response (Hill slope -4.69 ± 3.85, -4.03 ± 3.85; logED(50), 2.56 ± 0.09, 2.41 ± 0.12 nm, in PCOS and Control). Moreover, the SkBF-[BQ788] curve shifted to the right in women with PCOS, suggesting attenuated ET-B receptor mediated vasodilatation during local skin warming compared to Controls. Thus, the endothelium located ET-B receptors function similarly in women with and without PCOS, although with blunted responsiveness in women with PCOS. Our studies suggest that the lower ET-B receptor responsiveness associated with PCOS may reflect lower endothelial-mediated vasodilatation independent of generally lower vascular reactivity.
