Specific selection pressure at the third codon positions: contribution to 10- to 11-base periodicity in prokaryotic genomes.
Article in Journal of molecular evolution, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Prokaryotic sequences are responsible for more than just protein coding. There are two 10- to 11-base periodical patterns superimposed on the protein coding message within the same sequence. Positional auto- and cross-correlation analysis of the sequences shows that these two patterns are a short-range counter-phase oscillation of AA and TT dinucleotides and a medium-range in-phase oscillation of the same dinucleotides, spanning distances of up to approximately 30 and approximately 100 bases, respectively. The short-range oscillation is encoded by the amino acid sequences themselves, apparently, due to the presence of amphipathic alpha-helices in the proteins. The medium-range oscillation, related to DNA folding in the cell, is created largely by a special choice of the bases in the third positions of the codons. Interestingly, the amino acid sequences do contribute to that signal as well. That is, the very amino acid sequences are, to some extent, degenerate to serve the same oscillating pattern that is associated with the degenerate third codon positions.
