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

A gamma interferon (IFN-gamma)-dependent innate immune response operates against the intestinal parasite Cryptosporidium parvum in T- and B-cell-deficient SCID mice. Although NK cells are a major source of IFN-gamma in innate immunity, their protective role against C. parvum has been unclear. The role of NK cells in innate immunity was investigated using Rag2-/- mice, which lack T and B cells, and Rag2-/- gammac-/- mice, which, in addition, lack NK cells. Adult mice of both knockout lines developed progressive chronic infections; however, on most days the level of oocyst excretion was higher in Rag2-/- gammac-/- mice and these animals developed morbidity and died, whereas within the same period the Rag2-/- mice appeared healthy. Neonatal mice of both mouse lines survived a rapid onset of infection that reached a higher intensity in Rag2-/- gammac-/- mice. Significantly, similar levels of intestinal IFN-gamma mRNA were expressed in Rag2-/- and Rag2-/- gammac-/- mice. Also, infections in each mouse line were exacerbated by treatment with anti-IFN-gamma neutralizing antibodies. These results support a protective role for NK cells and IFN-gamma in innate immunity against C. parvum. In addition, the study implies that an intestinal cell type other than NK cells may be an important source of IFN-gamma during infection and that NK cells may have an IFN-gamma-independent protective role.
