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
Zika virus (ZIKV) can be vertically transmitted from a pregnant mother to the developing fetus, resulting in microcephaly and/or other congenital malformations. Dengue virus (DENV) cross-reactive antibodies can facilitate ZIKV placental transcytosis and enhance ZIKV infection of placenta macrophage-Hofbauer cells through binding to Fc-γ receptors (FcγRs). To understand the role of individual FcγR in antibody-mediated ZIKV placental infection, we generated a comprehensive panel of Fc-variants spanning a wide range of binding affinities to different FcγRs. We found that mutations with increased affinity to FcγRI strongly correlated with an increased frequency of infected pro-monocytic U937 and Hofbauer cells. Next, we genetically deleted individual FcγR in U937 cells, and found that the knockout of
