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
Secondary macrophage cell cultures were generated from the primary culture of epiblasts of 8-d-old pig blastocysts. The epiblast-derived macrophagelike (EDM) cells have a morphology and ameboid behavior that is typical of tissue histocytes. The cells reacted positively with monoclonal antibodies specific for pig granulocyte-macrophage lineage cells, and were not reactive with monoclonal antibodies specific for pig B and T lymphocytes. Marked phagocytic behavior and the formation of phagosomes were demonstrated following incubation with FITC-labeled bacteria. The EDM cells stained positively for nonspecific acid esterase that was not inhibited by sodium fluoride. DiI-acetylated-LDL was rapidly taken up by the cells. Transmission electron microscopy of the EDM cells showed phagolysosomes, numerous cytoplasmic vacuoles, large, lobed nuclei, and numerous pseudopods or filopodia at the cell surface. Strong reactivity of the cells with anti-CD14 monoclonal antibody was observed. Further, cytotoxic activity was produced from the EDM cells after exposure to lipopolysaccharide in a concentration and time-dependent manner. The cultures could be maintained and expanded for several months on STO co-culture. Their derivation from the epiblast of the pig demonstrates the possibility of obtaining hemopoietic cell cultures from the preimplantation blastocysts of all mammals.
