Mannose supports lung cancer metabolism during glycolytic limitation.
Article in EMBO reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Cancer cells frequently show elevated glucose consumption to support proliferation and survival. This led to the assumption that glycolytic inhibitors could be effective in cancer treatment. However, barriers to clinical implementation remain. Adaptive strategies, such as metabolizing alternative nutrients, may play a role. Here, we investigated the use of an understudied sugar, mannose, in lung cancer cells and xenografts. Stable isotope tracing reveals enhanced contribution of mannose to GDP-mannose and GDP-fucose, key glycosylation precursors, upon treatment with the glycolytic inhibitor 2-deoxyglucose (2-DG) or glucose starvation in vitro. Mannose restores the glucose-withdrawal-induced decrease of GDP-mannose and GDP-fucose pools, and partially rescues proliferation upon 2-DG treatment or glucose deprivation.
