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

Pigs are emerging as important large animal models for biomedical research, and they may represent a source of organs for xenotransplantation. The MHC is pivotal to the function of the immune system in health and disease, and it is particularly important in infection and transplant rejection. Pigs deficient in class I MHC could serve as important reagents to study viral immunity as well as allograft and xenograft rejection. In this study, we report the creation and characterization of class I MHC knockout pigs using the Cas9 nuclease and guide RNAs. Pig fetal fibroblasts were genetically engineered using Cas9 and guide RNAs, and class I MHC(-) cells were then used as nuclear donors for somatic cell nuclear transfer. We produced three piglets devoid of all cell surface class I proteins. Although these animals have reduced levels of CD4(-)CD8(+) T cells in peripheral blood, the pigs appear healthy and are developing normally. These pigs are a promising reagent for immunological research.
