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

1. The effects of histamine, noradrenaline and caffeine were studied in freshly dispersed smooth muscle cells from the rabbit pulmonary artery using the perforated patch technique. 2. In potassium-containing solutions at a holding potential of -50 mV all three agents evoked net inward and outward currents. At 0 mV only an outward current was observed and this response was not produced in potassium-free conditions. 3. In K(+)-free solutions the reversal potential (Er) of the inward current was dependent upon the transmembrane anion gradient but not on the cation gradient. Thus all three agents produced an increase in potassium and chloride conductance. 4. Bath-applied histamine evoked repetitive potassium and chloride currents in many cells. Bath-applied noradrenaline and caffeine, to a lesser extent, also caused repetitive currents but the brief ionophoretic application of noradrenaline never produced oscillations in membrane current. 5. Histamine reduced or abolished the amplitude of spontaneous transient potassium and chloride currents. 6. Histamine-induced currents were blocked by caffeine (10 mM) but could be recorded in Ca(2+)-free bathing solutions. 7. It is concluded that in the rabbit pulmonary artery histamine evokes single and oscillatory membrane potassium and chloride currents which are mediated by the release of calcium from intracellular caffeine-sensitive stores.
