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

We provide here detailed electrophysiological protocols to study voltage-gated sodium channels and to investigate how wild-type and mutant channels influence firing properties of transfected mammalian dorsal root ganglion (DRG) neurons. Whole-cell voltage-clamp recordings permit us to analyze kinetic and voltage-dependence properties of ion channels and to determine the effect and mode of action of pharmaceuticals on specific channel isoforms. They also permit us to analyze the role of individual sodium channels and their mutant derivatives in regulating firing of DRG neurons. Five to ten cells can be recorded daily, depending on the extent of analysis that is required. Because of different internal solutions that are used in voltage-clamp and current-clamp recordings, only limited information can be obtained from recording the same neuron in both modes. These electrophysiological studies help to elucidate the role of specific channels in setting threshold and suprathreshold responses of neurons, under normal and pathological conditions.
