Charge-Driven Interaction of Antimicrobial Peptide NK-2 with Phospholipid Membranes.
Article in ACS omega, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
NK-2, derived from a cationic core region of NK-lysin, displays antimicrobial activity toward negatively charged bacterial membranes. We have studied the interaction of NK-2 with various phospholipid membranes, using a variety of experimental techniques, such as, isothermal titration calorimetry (ITC), ζ potential, and dynamic light scattering. As bacteria mimicking membranes, we have chosen large unilamellar vesicles (LUVs) composed of negatively charged phospholipid and neutral phospholipids. ITC and ζ potential results show the stronger binding affinity of NK-2 to negatively charged membranes than to neutral membranes. Saturation of the isotherm, obtained from ITC, at a given lipid to NK-2 ratio, was found to be consistent with the charge compensation, determined from ζ potential. A surface partition model with electrostatic contribution was used to estimate the intrinsic binding constant and other thermodynamical parameters of binding kinetics of NK-2. The size distribution of negatively charged LUV in the presence of NK-2 was found to increase drastically, indicating the presence of large aggregates. Such a large aggregate has not been observed in neutral membranes, which supports the ITC and ζ potential results.
