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
Alpha 2-macroglobulin (alpha 2M) is a serum proteinase inhibitor with a broad specificity. At present its role in human brain is unknown, but recent data report its presence in the CNS, particularly at glial level. Previous studies from our group demonstrated the synthesis and secretion of alpha 2M in different glial cultures derived from an astrocytoma and a glioblastoma. In the present study a human fetal astroglial cell line and two microglial established cell lines are examined for the presence of alpha 2M by using polyclonal antibodies in ELISA and immunofluorescence assays. While we observed a strong specific positivity in the cytoplasm and in the culture medium of the GFAP, vimentine positive cells, no positivity was detected in FcR, lysozyme positive microglial cells. Since interaction of proteinases and proteinase inhibitors appear to play a crucial role in the development of neuroimmunological competence, these data suggest a dissociation of macro and micro-glia immune functions.
