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

Peripheral blood leukocytes were collected from 5 Thoroughbred horses and examined for the presence of EHV2 in sub-populations of mononuclear cells. Peripheral blood mononuclear cells were separated on Percoll gradients and then enriched for plastic adherent cells (predominantly monocytes), surface immunoglobulin positive (sIg+) B lymphocytes and T lymphocytes, using panning techniques. The purity of each cell population was assessed by fluorescence activated cell scanning. In an infectious centre assay, each cell population was inoculated onto equine foetal kidney monolayer cell cultures which are fully permissive for the replication of EHV2. Only enrichment for sIg+ B lymphocytes resulted in a marked increase in the number of infectious centres, indicating that EHV2 is present in B lymphocytes. Freeze-thawing of sIg+ B lymphocytes, prior to inoculation onto EFK monolayer cell cultures, resulted in the complete abrogation of infectious centre formation, confirming that EHV2 is latent in B lymphocytes i.e., infectious free virus was not present in the cells. The number of EHV2 infected B lymphocytes varied considerably between horses from 4 to 780 per 10(6) cells. Evidence was also obtained that direct cell to cell contact between the epithelial cells and sIg+ B lymphocytes was necessary for the production of infectious centres. The data indicate that EHV2, like other members of the Gammaherpesvirinae, is latent within B lymphocytes.
