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

Our understanding of the complement system continues to grow beyond that of a liver-derived systemically operative mechanism of pathogen clearance to a central orchestrator of single-cell behavior and tissue biology. These expanded activities reflect the extrahepatic and local production of complement by many, if not most, cells, and the unexpected recent finding that complement also serves important physiological intracellular roles. The complement core component C3 has emerged as a particularly critical player in basic cell functions. Here, we provide an overview of the currently known forms and functions of intracellular C3 and the mechanisms that control it. We also discuss 2 emerging concepts as potential key areas for future exploration: intracellular C3 as a second layer of pathogen defense at host-environmental interfaces and "C3 licensing." We conclude by suggesting that the potential clinical implications surrounding perturbations in intracellular C3 activities should be explored better.
