1 · What the graph read from it

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.

2 · The registry

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

Glioblastoma (GBM) contains mesenchymal cancer stem cells that drive tumor aggressiveness and recurrence and exhibit aberrant glycosylation during proneural-to-mesenchymal transition. A comprehensive computational analysis of human GBM transcriptomic datasets revealed an up-regulation of 13 genes involved in glycan mannosylation compared to normal brain, and histopathological staining of a tissue array representing 35 GBM cases revealed elevated mannose levels that correlated with increased expression of the mesenchymal marker CD44. Hydroxyl proton transfer-weighted magnetic resonance imaging (HPTw MRI) detected elevated mannose levels in aggressive human mesenchymal GBM in vitro and in vivo but not in GBM with a less aggressive nonmesenchymal phenotype. To establish causation over correlation, inhibiting expression of the mannose-binding lectins LMAN1/2 that regulate intracellular processing of mannosylated proteins decreased the glioma cell HPTw MRI signal. Our findings indicate that HPTw MRI correlates with high mannose and possibly other saccharide levels in mesenchymal GBM cells, serving as a surrogate imaging biomarker for predicting tumor aggressiveness and recurrence.
