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
Nucleotide binding site (NBS)-leucine-rich repeat (LRR) genes belong to the largest class of disease-resistance gene super groups in plants, and their intra- or interspecies nucleotide variations have been studied extensively to understand their evolution and function. However, little is known about the evolutionary patterns of their copy numbers in related species. Here, 129, 245, 239 and 508 NBSs were identified in maize, sorghum, brachypodium and rice, respectively, suggesting considerable variations of these genes. Based on phylogenetic relationships from a total of 496 ancestral branches of grass NBS families, three gene number variation patterns were categorized: conserved, sharing two or more species, and species-specific. Notably, the species-specific NBS branches are dominant (71.6%), while there is only a small percentage (3.83%) of conserved families. In contrast, the conserved families are dominant in 51 randomly selected house-keeping genes (96.1%). The opposite patterns between NBS and the other gene groups suggest that natural selection is responsible for the drastic number variation of NBS genes. The rapid expansion and/or contraction may be a fundamentally important strategy for a species to adapt to the quickly changing species-specific pathogen spectrum. In addition, the small proportion of conserved NBSs suggests that the loss of NBSs may be a general tendency in grass species.
