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
Control of IgG immune complex formation and deposition is important in determining the nature and extent of subsequent immune effector responses, and appears to be aberrant in some autoimmune diseases. In this study we demonstrate that recombinant soluble Fc gamma RII (rsFc gamma RII) is an effective modulator of immune complex formation, delaying immune precipitation in a manner which is dose-dependent, and can be specifically inhibited by anti-Fc gamma RII MoAb Fab' fragments. This inhibitory role in immune precipitation also provides a possible mechanistic explanation for our previous demonstration of the efficacy of rsFc gamma RII as an inhibitor of immune complex-induced inflammation in the Arthus reaction in vivo. RsFc gamma RII inhibited immune complex precipitation in two different experimental systems. First, rsFc gamma RII inhibited the precipitation of 125I-bovine serum albumin (BSA)-anti-BSA complexes in a dose-dependent manner, while an irrelevant protein (soybean trypsin inhibitor) had no effect on the precipitation of the immune complexes. Moreover, rsFc gamma RII inhibited the precipitation of ovalbumin (OVA)-anti-OVA complexes as determined by turbidimetric analysis, where the inhibition of immune complex precipitation by rsFc gamma RII was dose-dependent and was specifically blocked by prior incubation with Fab' fragments of a blocking MoAb to Fc gamma RII. RsFc gamma RII could inhibit the precipitation of BSA-anti-BSA complexes in the presence of excess bystander IgG and did not inhibit complement-mediated prevention of immune precipitation, demonstrating that rsFc gamma RII did not block C1 binding to the BSA-anti-BSA complex. Unlike complement, rsFc gamma RII could not cause re-solubilization of pre-formed precipitated BSA-anti-BSA complexes. Soluble Fc gamma Rs have been detected in biological fluids of normal and inflammatory disease patients, yet the role of sFc gamma R is still unclear. However, they now play a potential role in the modulation of immune complex solubility.
