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

It is not clear whether matK evolves under Darwinian selection. In this study, 70 plant groups, representing 2,279 species at various evolutionary levels, were used to illustrate the molecular adaptation and evolutionary dynamics of gene divergence in matKs. Selective influences were investigated using standard dN/dS ratio methods. Analyses revealed the presence of positive selection in matKs of 32 plant groups. More positively selected sites were detected in the N-terminal region than in the RT domain and domain X of matK. Moreover, removing amino acid sites that are under positive selection has a significant effect on the bootstrap values of phylogenetic reconstruction. Our results suggest that the rapidly evolving matK evolves under positive selection in some lineages of land plants. Several regions of matK have experienced molecular adaptation, which fine-tunes maturase performance.
