Behavioral differences between phosphatidic acid and phosphatidylcholine in the presence of the nicotinic acetylcholine receptor.
Article in Biophysical journal, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
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
It has been found experimentally that negatively charged phosphatidic acid (PA) lipids and cholesterol molecules stabilize the nicotinic acetylcholine receptor (nAChR) in a functional resting state that can participate in an agonist-induced conformational change. In this study, we compare phosphatidylcholine (PC) and PA lipid behavior in the presence of the nAChR to determine why PC lipids do not support a functional nAChR. For lipids that are located within 1.0 nm of the protein, both PC and PA lipids have very similar order-parameter and bilayer-thickness values, which indicate that the annular lipid properties are protein-dependent. The most significant difference between the PC and PA bilayers is the formation of a lipid domain around the protein, which is visible in the PA bilayer but not the PC bilayer. This suggests that the PA domain may help stabilize the nAChR resting state. The PA lipids in the microdomain have a decreased order compared to a homogeneous PA bilayer and the lipids near the protein attempt to increase the free space in their vicinity by residing in multiple lateral planes.
