Article in Journal of cerebral blood flow and metabolism : official journal of the International Society of Cerebral Blood Flow and Metabolism, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04088630 (Fingolimod as a Treatment of Cerebral Edema After Intracerebral Hemorrhage), which is not on this map. Cited by 49 papers.

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.

Abstract

Intracerebral hemorrhage (ICH) is a stroke subtype with high rates of mortality and morbidity. The immune system, particularly complement and cytokine signaling, has been implicated in brain injury after ICH. However, the cellular immunology associated with ICH has been understudied. In this report, we use flow cytometry to quantitatively profile immune cell populations that infiltrate the brain 1 and 4 days post-ICH. At 1 day CD45(hi) GR-1(+) cells were increased 2.0-fold compared with saline controls (P<or=0.05); however, we did not observe changes in any other cell populations analyzed. At 4 days ICH mice presented with a 2.4-fold increase in CD45(hi) cells, a 1.9-fold increase in CD45(hi) GR-1(-) cells, a 3.4-fold increase in CD45(hi) GR-1(+) cells, and most notably, a 1.7-fold increase in CD4(+) cells (P<or=0.05 for all groups), compared with control mice. We did not observe changes in the numbers of CD8(+) cells or CD45(lo) GR-1(-) cells (P=0.43 and 0.49, respectively). Thus, we have shown the first use of flow cytometry to analyze leukocyte infiltration in response to ICH. Our finding of a CD4 T-cell infiltrate is novel and suggests a role for the adaptive immune system in the response to ICH.
