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
An allotypic form of the low affinity IgG Fc receptor Fc gamma RIIa (CD32), termed low responder (LR) because of its weak reactivity with mouse (m) IgG1, interacts efficiently with human (h) IgG2. Fc gamma RIIaLR is the first known human FcR that binds this IgG subclass. In this study, we analyzed the role of Fc gamma RIIa in binding of stable hIgG-subclass dimers, and in induction of T cell mitogenesis using chimeric anti-CD3 mAb. We demonstrate that the functional polymorphism to hIgG2 is expressed on the majority of Fc gamma R-bearing peripheral blood cells: monocytes, neutrophils, and platelets. We were able to assess Fc gamma RII-mediated IgG-binding without interference of other Fc gamma R-classes, by blockade of Fc gamma RI on monocytes, and by using neutrophils of an individual deficient for the Fc gamma RIIIB gene. This study indicates as subclass specificity: hIgG3 >hIgG1,hIgG2 >> hIgG4 for Fc gamma RIIaLR and hIgG3,hIgG1 >> hIgG2 > hIgG4 for Fc gamma RIIaHR. Comparing the serum hIgG levels of individuals homozygous for the two fc gamma RIIa allotypic forms, we observed significantly lower hIgG2 serum levels in individuals expressing the hIgG2-binding LR allotypic form. This observation may implicate that Fc gamma RIIa regulates hIgG subclass production or turnover in man.
