Computational study of the Na+/H + antiporter from Vibrio parahaemolyticus.
Article in Journal of molecular modeling, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Sodium proton antiporters are ubiquitous membrane proteins that catalyze the exchange of Na(+) for protons throughout the biological world. The Escherichia coli NhaA is the archetypal Na(+)/H(+) antiporter and is absolutely essential for survival in high salt concentrations under alkaline conditions. Its crystal structure, accompanied by extensive molecular dynamics simulations, have provided an atomically detailed model of its mechanism. In this study, we utilized a combination of computational methodologies in order to construct a structural model for the Na(+)/H(+) antiporter from the gram-negative bacterium Vibrio parahaemolyticus. We explored its overall architecture by computational means and validated its stability and robustness. This protein belongs to a novel group of NhaA proteins that transports not only Na(+) and Li(+) as substrate ions, but K(+) as well, and was also found to miss a β-hairpin segment prevalent in other homologs of the Bacteria domain. We propose, for the first time, a structure of a prototype model of a β-hairpin-less NhaA that is selective to K(+). Better understanding of the Vibrio parahaemolyticus NhaA structure-function may assist in studies on ion transport, pH regulation and designing selective blockers.
