Penetration of lysozyme and cytochrome C in lipid bilayer: fluorescent study.
Article in The Journal of membrane biology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Lysozyme and cytochrome c (CytC) are well-investigated proteins. Their specific interactions with lipid membranes, however, keep surprising secrets. Lysozyme destroys bacterial membrane; CytC binds hydrophobically to alkyl chains of the membrane lipid tails, indicating that both proteins are able to interact directly with the inner membrane components, especially with the fatty acyl chains of membrane lipids. The degrees of integration, depth of localization in the hydrophobic interior of different types of model membranes, and the type of interaction of lysozyme and CytC with surrounding lipids were investigated by fluorescent spectroscopy. Three different fluorescent markers, located at approximately 6.5, 9, and 18 Å into the lipid bilayer, were used. In addition, liposomes were designed as electrically neutral or positively or negatively charged to unravel the importance of the net electrical charge for lipid/protein interaction. CytC penetrates deeper into the lipid bilayer in comparison with lysozyme, and data are discussed in the terms of Stern-Volmer quenching of fluorescence.
