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 fundamental property of P2X7 receptor (P2X7R) channels is the transport of cations across the cell surface membrane. Electrophysiology and patch-clamp photometry are readily accessible methods of measuring this flux in a wide range of cell types. They are important tools used to characterize the functional properties of native cells studied in cell culture, in vitro tissue slices, and, in some cases, in situ single cells. Further, they are efficient methods of probing the relation of structure to function of recombinant receptors expressed in heterologous systems. Here, we provide step-by-step procedures for use of two standard recording protocols, broken-patch and perforated-patch voltage clamp. Further, we describe a third technique, called the dye-overload method, that uses simultaneous measurement of membrane current and fura-2 fluorescence to quantify the contribution of Ca
