The interaction of monoclinic calcium pyrophosphate dihydrate crystals with neutrophils.
Article in Rheumatology international, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Monoclinic calcium pyrophosphate dihydrate (m-CPPD) crystals were synthesized and characterized using physical methods, IgG binding to m-CPPD crystals was quantitated, and the effect of IgG or plasma opsonization on m-CPPD-induced neutrophil activation was determined. Adsorption of IgG to crystals was measured using fluorescent-labelled FITC-IgG. Neutrophil activation by uncoated m-CPPD and crystals precoated with IgG or plasma was measured using luminol-enhanced chemiluminescence, superoxide anion generation, and myeloperoxidase release. m-CPPD bound small (compared to triclinic CPPD) but significant amounts of IgG and induced a strong activation of neutrophils at low concentrations of crystals. The rate and extent of chemiluminescence, superoxide anion production, and degranulation was not affected by precoating m-CPPD crystals with IgG during the early phase of neutrophil responses, but was inhibited by the precoating of crystals with plasma.
