Pertussis toxin does not affect the adenosine-induced inhibition of the efferent function of cardiac capsaicin-sensitive nerves.
Article in Journal of neural transmission. General section, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The negative inotropic effect of adenosine (1-100 microM) was abolished in isolated guinea-pig atria obtained from pertussis toxin-pretreated guinea pigs electrically driven at 4 Hz. However, the inhibitory effect of the same concentrations of adenosine on the cardiac response to stimulation of non-adrenergic non-cholinergic (NANC), capsaicin-sensitive sensory nerves, was not modified by the toxin. These results suggest that, while pertussis toxin-sensitive G proteins are involved in the negative inotropic effect of adenosine, they do not mediate the inhibitory effect of adenosine on cardiac NANC neurotransmission.
