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

Endogenous viral elements serve as molecular fossils of ancient viral infections, providing valuable evidence for reconstructing the evolutionary history of modern viruses and their hosts. These genomic remnants also provide crucial benchmarks for calibrating viral evolutionary timelines. Here, our flanking sequence analysis reveals that densovirus NS1 sequences are chromosomally integrated in Platyhelminth genomes. Furthermore, their evolutionary dynamics reflect an ancient host-virus codivergence event dating to the Ediacaran-Cambrian transition (approximately 692 million years ago, MYA). Phylogenomic analyses delineate profound divergence between endogenous densovirus sequences in Platyhelminthes and exogenous Parvoviridae sequences, with distinct phylogenetic clustering supporting long-term endogenization. Structural alignments reveal significant global divergence (RMSD: 15.048-36.725 Å) yet striking local conservation in NS1 proteins, with the ATPase (RMSD: 0.271-1.756 Å) and effector domains (RMSD: 2.446-4.775 Å) remaining highly conserved across Platyhelminth hosts. The timescale phylogenetic tree inferred ancient divergence times of 233.51 MYA for
