1 · What the graph read from it

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.

2 · The registry

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

Analysis of the Arabidopsis thaliana, Saccharomyces cerevisiae, Mus musculus, Escherichia coli, Bacillus subtilis, Thermoplasma acidophilum, and Sulfolobus tokodaii genomes demonstrate that many amino acid biases occur at the N- and C-termini of proteins, a statistically significant number of these biases are evolutionarily conserved, and these biases occur in amino acids beyond the first and last five amino acids. Analyses designed to shed light on the mechanism causing amino acid biases suggest that in at least some cases the bias is caused by forces acting at the nucleic acid level. It is also demonstrated that in E. coli functionally related proteins show similar biases at the N- and C-termini suggesting that the mechanisms causing the biases are complex and in some cases are related to function.
