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 annexins are a family of structurally similar, Ca2(+)-dependent, phospholipid-binding proteins. We compared six members of this family (calpactin I heavy chain, lipocortins I and III, endonexin II, p68 and protein II) to determine their phospholipid-binding specificities, as well as their ability to promote aggregation and fusion of phospholipid vesicles. The Ca2+ requirement for all of the proteins was lowest for binding to vesicles composed of phosphatidic acid, followed by phosphatidylserine and then phosphatidylinositol. Only protein II, p68, lipocortin III and endonexin II bound to vesicles composed of phosphatidylethanolamine, and none bound to phosphatidylcholine. Both calpactin I heavy chain and lipocortin I promoted aggregation of phosphatidylserine- or phosphatidylinositol-containing vesicles in the presence of less than 10 microM-Ca2+. Lipocortin I promoted fusion of liposome membranes by lowering threshold Ca2+ concentrations. Although calpactin I heavy chain did not affect threshold Ca2+ concentrations, it did increase the rate and extent of spontaneous fusion. In contrast, p68 inhibited fusion at threshold Ca2+ concentrations. Whereas previous reports have emphasized properties that the annexins have in common, these findings reveal quantitative and qualitative differences among the annexins which may relate to distinct intracellular functions.
