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

The evolutionary relationships between transfer RNA (tRNA) molecules are analyzed by parsimony algorithms. The position of the topologies expected on the basis of the hypotheses made to explain the origin of the genetic code, on the frequency distribution of all the possible tree topologies of the evolutionary relationships between tRNAs seems to lead to the following conclusion: The hypothesis (Wong, J. T., Proc. Natl. Acad. Sci. USA, 1975, 72: 1909-1912) that sees the genetic code as a map of the biosynthetic relationships between amino acids seems to occupy a statistically significant position on these frequency distributions, thus reflecting a significant part of the tRNA phylogeny.
