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

CD8(+) cytotoxic T lymphocytes play a major role in defense against intracellular pathogens, and their functions are specified by antigen recognition and innate cytokines. IL-12 and IFN-α/β are potent "signal 3" cytokines that are involved in both effector and memory cell development. Although the majority of effector cells are eliminated as inflammation resolves, some survive within the pool of memory cells and retain immediate effector function. In this study, we demonstrate that IL-12 instructs a unique program of effector cell differentiation that is distinct from IFN-α/β. Moreover, effector memory (T(EM)) cells within peripheral blood display many common attributes of cells differentiated in vitro in response to IL-12, including proinflammatory cytokine secretion and lytic activity. A pattern of IL-12-induced genes was identified that demarcate T(EM) from central memory cells, and the ontologies of these genes correlated precisely with their effector functions. Further, we uncovered a unique program of gene expression that was acutely regulated by IL-12 and reflected in stable gene expression patterns within T(EM), but not T central memory cells in vivo. Thus, this study directly links a selective set of IL-12-induced genes to the programming of effector functions within the stable population of human CD8(+) T(EM) cells in vivo.
