Activation of human neutrophils by calcium carbonate polymorphs.

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.
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
Gallstone formation is frequently accompanied by inflammation of the gallbladder mucosa. Some gallstone components such as cholesterol, calcium bilirubinate, and calcium hydroxyapatite have been previously shown to activate neutrophils. We investigated the effect on neutrophils of the calcium carbonate polymorphs aragonite, calcite, and vaterite (all found in gallstones). By chemiluminescence, superoxide, and degranulation assay, all three crystals were shown to cause rapid activation of neutrophils. The potency of the crystals was aragonite > vaterite > calcite. In vivo, crystals may be plasma-protein-coated before they encounter neutrophils; therefore some experiments were repeated using crystals that had been preincubated with plasma. For aragonite and vaterite, protein adsorption decreased the chemiluminescence response by approximately 50%. In contrast, protein-coated calcite crystals elicited a greater chemiluminescence response than did uncoated crystals. In summary, the calcium carbonate polymorphs are potent activators of neutrophils and thus have the potential to contribute to gallstone-associated cholecystitis.
