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
Signaling by fibroblast growth factor 2 (FGF-2), an autocrine stimulator of glioma growth, is regulated by heparan sulfate proteoglycans (HSPGs) via a ternary complex with FGF-2 and the FGF receptor (FGFR). To characterize glioma growth signaling, we examined whether altered HSPGs contribute to loss of growth control in gliomas. In a screen of five human glioma cell lines, U118 and U251 cell HSPGs activated FGF-2 signaling via FGFR1c. The direct comparison of U251 glioma cells with normal astrocyte HSPGs demonstrated that the glioma HSPGs had a significantly elevated ability to promote FGF-2-dependent mitogenic signaling via FGFR1c. This enhanced activity correlated with a higher level of overall sulfation, specifically the abundance of 2S- and 6S-containing disaccharides. Glioma cell expression of the cell-surface HSPG glypican-1 closely mirrored the FGF-2 coactivator activity. Furthermore, forced expression of glypican-1 in (glypican-1-deficient) U87 glioma cells enhanced their FGF-2 response. Immunohistochemical analysis revealed a highly significant overexpression of glypican-1 in human astrocytoma and oligodendroglioma samples compared with nonneoplastic gliosis. In summary, these observations suggest that altered HSPGs contribute to enhanced signaling of FGF-2 via FGFR1c in gliomas with glypican-1 playing a significant role in this mitogenic pathway.
