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 notion that modern metabolism was derived from a complex 'RNA world' in which most reactions were catalyzed by ribozymes has received wide acceptance. However, the evolutionary links between the first self-replicating systems and ribozymes as complex as, say, the Group I self-splicing intron or the HDV ribozyme, have remained elusive. While prebiotic chemists have succeeded in synthesizing short oligonucleotides, it is not immediately obvious how these could have replicated and evolved to the point where they could assume complex shapes and catalytic functions. Nonetheless, recent experiments from a variety of disciplines suggest a plausible pathway from prebiotic chemistry to complex metabolism, and this review is intended as a hypothetical roadmap for the origin and subsequent evolution of life.
