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.
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 DEAD box RNA helicase (RH) proteins are homologs involved in diverse cellular functions in all of the organisms from prokaryotes to eukaryotes. Nevertheless, there is a lack of conservation in the splicing pattern in the 53 Arabidopsis thaliana (AtRHs), the 32 Caenorhabditis elegans (CeRHs) and the 29 Drosophila melanogaster (DmRHs) genes. Of the 153 different observed intron positions, 4 are conserved between AtRHs, CeRHs, and DmRHs, and one position is also found in RHs from yeast and human. Of the 27 different AtRH structures with introns, 20 have at least one predicted ancient intron in the regions coding for the catalytic domain. In all of the organisms examined, we found at least one gene with most of its intron predicted to be ancient. In A. thaliana, the large diversity in RH structures suggests that duplications of the ancestral RH were followed by a high number of intron deletions and additions. The very high bias toward phase 0 introns is in favor of intron addition, preferentially in phase 0. Results from this comparative study of the same gene family in a plant and in two animals are discussed in terms of the general mechanisms of gene family evolution.
