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 root of the tree of life remains a controversial issue in the study of the origins and evolution of early life on Earth, and so is the origin and evolution of early biochemistry. Here, we describe the methodological procedures of reconstructing global phylogenies of early life based on RNA secondary structure, with the rooting of phylogenies developed and improved to ultimately gain insights into the deep evolution of ancient molecules. As an example, we explore the evolution of the transfer RNA (tRNA) molecules using statistical characters describing their structure. An evolutionary model of molecular accretion of tRNA modeled at the atomic level illustrates the experimental exercise.
