Vasomotor and fibrinolytic responses to kinin receptor agonists in the atherosclerotic human lower limb.
Trial report in Heart and vessels, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
Upregulation of vascular B(1) kinin receptor expression has been reported in human atheroma, but its role remains unclear. We examined vasomotor and fibrinolytic responses to selective B(1) and B(2) kinin receptor agonism in the human femoral circulation and correlated responses with femoral arterial plaque load. Femoral arterial cross-sectional area, blood flow and plaque volume were determined using intravascular ultrasound and Doppler during selective arterial infusion of Lys-des-Arg(9)-bradykinin (B(1) agonist), bradykinin (B(2) agonist) and sodium nitroprusside in eleven patients undergoing diagnostic coronary angiography. Net release of tissue plasminogen activator was determined across the femoral vascular bed. Mean femoral arterial plaque load was 8.1 (±0.9) mm(3)/mm of vessel. Bradykinin and sodium nitroprusside caused dose-dependent increases in femoral blood flow (p < 0.05 and p < 0.005, respectively). Bradykinin caused a dose-dependent increase in net tissue plasminogen activator release (p < 0.05), which was augmented by angiotensin-converting enzyme inhibition (p < 0.05). There were no correlations between plaque load and bradykinin-mediated vasodilation or tissue plasminogen activator release. Lys-des-Arg(9)-bradykinin had no effect on blood flow or tissue plasminogen activator release. The vasomotor and fibrinolytic actions of bradykinin in the femoral circulation are mediated solely by the B(2) kinin receptor, irrespective of the presence of atheroma. In keeping with previous data, bradykinin-mediated tissue plasminogen activator release was augmented in the presence of angiotensin-converting enzyme inhibition consistent with its putative vascular protective effect.
