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

Different Suiformes with increasing phylogenetic distance to the common pig (Sus scrofa) were assayed for the presence of porcine endogenous retroviruses (PERV) in general (pol gene), while the distribution of long terminal repeat (LTR) types (with or without repeats in U3) and env genes (classes A, B, and C) were determined in detail. PERV was not detectable in the most distantly related species, while classes PERV-A and PERV-B are present in Suiformes originating in the Pliocene epoch, and class PERV-C was detectable only in S. scrofa and in closely related species originating in the Holocene epoch. This distribution pattern of PERV classes is in line with our previous study on the age of PERV (45) and suggests an African origin of about 7.5 million years ago (MYA) and a gradual spread of PERV through the Suiformes. It seems likely that PERV-C originated more recently (1.5 to 3.5 MYA) by recombination with a homologue of unknown descent, while the origin of the repeatless LTR was a separate event approximately 3.5 MYA.
