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

Paired receptors are groups of closely related membrane proteins that have the potential to either inhibit or activate. The CD200R family consists of one inhibitory member, CD200R and various numbers of activating genes according to species with three defined in C57BL/6 mice. A genomic PCR strategy was used to examine the repertoire of genes in both laboratory and wild-derived mice. Most mouse strains tested (18/22) had three activating genes, and 16 of these had either the combination of CD200RLa, Lb, and Lc or CD200RLa, Lb, and Le. The Lc and Le genes were mutually exclusive and were equally common (10 strains). Wild-derived mice varied more with one example of strains with one, two, and four activating genes. An inhibitory CD200R gene was detected in each mouse strain, although two slightly different sequences were found in both laboratory and wild-derived mice. This diversity is probably being driven by pathogens but is less extensive than for many NK paired receptors such as KIR and Ly49. It is possible that myeloid paired receptors are involved in immune regulation of responses against pathogens rather than directly killing infected cells as for NK cells and, hence, under less intense evolutionary pressure.
