Human neutrophil antigen-3a antibodies induce neutrophil aggregation in a plasma-free medium.

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
backgroundAntibodies against the human neutrophil alloantigen-3a (HNA-3a) are involved in severe cases of transfusion-related acute lung injury (TRALI), but the susceptibility of patients towards HNA-3a antibody differs largely. HNA-3a antibodies induce granulocyte aggregation. However, it is unresolved whether plasma proteins are required for granulocyte aggregation. MATERIALS AND
methodsWe investigated whether HNA-3a-antibody-induced aggregation of polymorphonuclear cells is dependent on plasma factors by using and modifying the granulocyte agglutination test (GAT).
resultsPolymorphonuclear cells homozygous for HNA-3a did not aggregate when incubated with HNA-3a antibodies in a plasma-protein-free GAT setup. When the GAT was performed using polymorphonuclear cells re-suspended in phosphate-buffered saline containing proteins, HNA-3-mediated aggregation was observed. Moreover, using Tween® 20 for blocking the plates, reconstituted the granulocyte aggregation in a protein-free medium. This indicates that granulocyte aggregation probably occurs by direct granulocyte-granulocyte interaction(s) or is mediated by substances released by neutrophils after activation. DISCUSSION: Granulocyte aggregation induced by HNA-3a antibodies does not require human plasma proteins. Interindividual variability in the response to HNA-3a antibodies does not depend on differences in patient's plasma proteins.
