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

Structurally distinct nicotinic and P2X channels interact functionally, such that coactivation results in cross-inhibition of one or both channel types. It is hypothesized, but not yet proven, that nicotinic and P2X channels interact at the plasma membrane. Here, we show that plasma membrane alpha4beta2 nicotinic and P2X2 channels form a molecular scale partnership and also influence each other when coactivated, resulting in nonadditive cross-inhibitory responses. Total internal reflection fluorescence and fluorescence resonance energy transfer microscopy between fluorescently labeled P2X2 and alpha4beta2 nicotinic channels demonstrated close spatial arrangement of the channels in human embryonic kidney cells and in hippocampal neuron membranes. The data suggest that P2X2 and alpha4beta2 channels may form a dimer, with the channels approximately 80 A apart. The measurements also show that P2X2 subunits interact specifically and robustly with the beta2 subunits in alpha4beta2 channels. The data provide direct evidence for the close spatial apposition of full-length P2X2 and alpha4beta2 channels within 100 nm of the plasma membrane of living cells.
