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

The purpose of this investigation was to study the effect of adrenaline on presynaptic adrenoceptors by recording the release of 3H-noradrenaline evoked by electrical-field stimulation. Adrenaline (10(-10)-3 x 10(-9) mol/l) had no effect on the 3H-overflow evoked by stimulation of aorta preloaded with 3H-noradrenaline. At 10(-8) and 3 x 10(-8) mol/l, the 3H-overflow was decreased by up to 47%. The maximum decrease was more marked in the presence of either cocaine (3 x 10(-5) mol/l) plus corticosterone (4 x 10(-5) mol/l), cocaine (3.3 x 10(-6) mol/l) plus normetanephrine (4 x 10(-5) mol/l), or desipramine (10(-6) mol/l) plus normetanephrine (10(-5) mol/l). The relationship between adrenaline-induced decrease and stimulation-frequency was dependent on the experimental design: either the decrease was the same at all frequencies (1-16 Hz) or it was more marked, the lower the frequency (1 greater than 3 greater than 8 Hz). Phentolamine and rauwolscine (both 10(-6) mol/l) antagonized the inhibitory effect of adrenaline (10(-8)-10(-6) mol/l). Phenoxybenzamine (10(-6) mol/l), prevented the inhibitory effect. No enhancing effect of adrenaline (10(-9)-10(-6) mol/l) was observed in the presence of these three alpha-adrenoceptor antagonists. Our results suggest that adrenaline activates inhibitory alpha 2-adrenoceptors, but not facilitatory beta-adrenoceptors on postganglionic sympathetic nerve terminals in rabbit aorta.
