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

Positive regulatory domain member (PRDM) family proteins play important roles in nervous system development, neural stem cell proliferation and differentiation, and central nervous system inflammation. The unique evolutionary position of the lamprey (Lethenteron reissneri) as one of the oldest jawless vertebrates makes it an ideal animal model for understanding vertebrate evolution. Nevertheless, the evolutionary characteristics of PRDM genes have not yet been demonstrated in lampreys. In this study, we identified PRDM1, 4, 5, 8, 12, 14, and 15 genes in the lamprey genomes and also investigated their evolutionary relationships through phylogenetic analysis. The characterization of PRDM genes appears to be conserved among vertebrates, as indicated by protein structural domain, motif, and 3D structure analysis. Genomic synteny analysis revealed that lamprey PRDM neighbor genes are significantly different from those of jawed vertebrates. Real-time quantitative results demonstrate that the PRDM gene family may be involved in immune defense and spinal cord injury (SCI) repair. This study not only enriches the understanding of PRDM gene evolution but also provides new clues for the Lr-PRDMs' roles in immune defense and SCI.
