The influence of tocolytic drugs on cardiac function, large arteries, and resistance vessels.
Trial report in European journal of clinical pharmacology, 2011. 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
purposeBeta-2 adrenoceptor agonistic drugs like ritodrine have been the reference tocolytic drugs, but are associated with cardiovascular side-effects. Atosiban, a newer drug, is a competitive antagonist of oxytocin and has been claimed to have fewer cardiovascular side effects. Until now, there has mainly been a subjective reporting of adverse reactions and few objective cardiovascular data. Evaluation of the acute effects of therapeutic doses of ritodrine and atosiban compared with placebo on cardiac function, large artery properties, blood pressure, and resistance vessels.
methodsA double-blind, randomized trial was carried out in 20 non-pregnant female volunteers. Hemodynamic measurements were made under standardized conditions during kinetic steady state. Cardiac output was measured with echocardiography, large artery properties with an echo-tracking device. The effect on the microcirculation was estimated using the total peripheral resistance index (TPRI).
resultsAtosiban did not differ from placebo. With ritodrine, cardiac function increased by 79% compared with placebo because of a rise in heart rate (91%). TPRI decreased by 48%. Ritodrine increased the distensibility of the common carotid artery by 62% and the compliance by 83%, independent of blood pressure. Compliance of the common femoral artery increased independently of pressure by 33% and the distensibility by 59%. Aortic pulse wave velocity was not influenced by either medication.
conclusionsThe present study shows potential beneficial vascular effects of ritodrine that are counterbalanced by the cardiac effects. Atosiban has no clinically relevant cardiovascular effects and may be a good alternative for ritodrine in pregnant women at risk of cardiovascular complications.
