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

10 and 30 mM 2,3-butanedione monoxime (BDM) applied extracellularly to voltage-clamped frog skeletal muscle twitch fibres suppressed both Ca2+ release flux and intramembranous charge movement. Both effects could be clearly separated. The early peak of the Ca2+ release flux was suppressed at every test voltage. The steady level attained at the end of a 100 ms clamp depolarization was relatively spared for lower depolarizing pulses, but was as suppressed as the peak at voltages above -20 mV. The intramembranous charge movement was affected mainly in the I gamma component. The drug had a distinct effect on the kinetics of the intramembranous charge movement current around the threshold for Ca2+ release. The three kinetic components of I gamma were simultaneously affected. For more positive depolarizations where the kinetic effect was not evident, the oxime had no significant effect on the charge moved. Under conditions in which I gamma was absent (i.e. stretched fibres, intracellular solutions containing 6 to 10 mM BAPTA), treatment with 10 mM BDM had a small, not significant suppressive effect on the maximum charge moved (Qmax), while it affected Ca2+ release significantly. When 10 mM BDM was applied in the presence of 0.2 mM tetracaine, the local anaesthetic-resistant Ca2+ release flux was not further suppressed by the oxime.
