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

The role of the glucocorticoid-regulated protein annexin 1 during the process of phagocytosis has been studied using annexin 1 null peritoneal macrophages. Wild type and annexin 1 null macrophages were incubated with several distinct phagocytic targets. No differences were observed in rate or the maximal response with respect to IgG complexes or opsonised zymosan phagocytosis, as assessed by monitoring the production of reactive oxygen species. When annexin 1 null macrophages were incubated with non-opsonised zymosan particles, they exhibited impaired generation of reactive oxygen species, which was linked to a defect in binding of cells to the particles, as determined with fluorescent zymosan. This phenomenon was further confirmed by electron microscopy analysis, where annexin 1 null macrophages internalised fewer non-opsonised zymosan particles. Specific alterations in macrophage plasma membrane markers were observed in the annexin 1 null cells. Whereas no differences in dectin-1 and FcgammaR II/III expression were measured between the two genotypes, decreased membrane CD11b and F4/80 levels were measured selectively in macrophages lacking annexin 1. These cells also responded with an enhanced release of PGE(2) and COX-2 protein expression following addition of the soluble stimulants, LPS and heat-activated IgG. In conclusion, these results suggest that participation of endogenous annexin 1 during zymosan phagocytosis is critical and that this protein plays a tonic inhibitory role during macrophage activation.
