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 Arabidopsis thaliana nuclear genome sequence revealed several open reading frames encoding proteins related to group II intron-encoded reverse transcriptase/maturases. Here, we show via sequence alignments that at least four such open reading frames are conserved in the nuclear genomes of A.thaliana and Oryza sativa (rice) and that they encode putative proteins belonging to two different classes (nMat-1 and nMat-2), neither of which is associated with a group II intron RNA structure. The two nMat-1 proteins have reverse transcriptase, maturase and DNA endonuclease domains characteristic of canonical group II intron-encoded proteins, while the two nMat-2 proteins have reverse transcriptase and maturase domains linked to a novel C-terminal domain. Although some nMat proteins have mutations expected to inactivate intron mobility functions, all could potentially retain the RNA splicing function. These nuclear maturase-like proteins may be imported into organelles to function in group II intron splicing and/or they may have assumed other cellular functions. Nuclear-encoded maturases could regulate organellar gene expression and may reflect a step in the evolution of mobile group II introns into spliceosomal introns.
