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

High quality reference genomes have facilitated the study of endogenous retroviruses (ERVs). However, there are an increasing number of published works which assume the ERVs in reference genomes are universal; even those of evolutionarily recent integrations. Consequently, these studies fail to properly characterise polymorphic ERVs, and even propose biological functions for ERVs that may not actually be present in the genomes of interest. Here, I outline the pitfalls of three studies of chicken endogenous Avian Leukosis Viruses (ALVEs or "ev genes": the "original" ERVs), all confounded by the assumption that the reference genome provides a representative ALVE baseline.
