Ribitol and ribose treatments differentially affect metabolism of muscle tissue in FKRP mutant mice.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Dystroglycanopathy is characterized by reduced or lack of matriglycan, a cellular receptor for laminin as well as other extracellular matrix proteins. Recent studies have delineated the glycan chain structure of the matriglycan and the pathway with key components identified. FKRP functions as ribitol-5-phosphate transferase with CDP-ribitol as the substrate for the extension of the glycan chain. Supplement of ribitol and ribose have been reported to increase the levels of CDP-ribitol in both cells and in muscles in vivo. Clinical trials with both ribitol and ribose have been reported for treating LGMD2I caused by mutations in the FKRP gene. Here we compared the comprehensive metabolite profiles of the skeletal muscle between ribitol-treated and ribose-treated FKRP mutant mice. The closely related pentose and pentitol show clearly differential impacts on metabolisms despite their similarity in enhancing the levels of CDP-ribitol and matriglycan synthesis. Supplement of ribitol changes lysophospholipid sub-pathway metabolite profiling with a trend towards normalization as reported in the muscle after AAV9-FKRP gene therapy. Ribose treatment significantly increases level of ribonate and elevates levels of advanced glycation end products. Further analysis is required to determine which metabolite is prudent to use for long-term daily treatment of dystroglycanopathies.
