Tracking Bone Loss in GLP-1RA Therapy: The Potential of the Deoxypyridinoline Urine Test.
Article in Diagnostics (Basel, Switzerland), 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
Skeletal safety of glucagon-like peptide-1 receptor agonists (GLP-1RAs) remains uncharted, with emerging evidence suggesting a divergence between mono- and dual-agonist therapies. GLP-1RA monotherapy appears bone-neutral, with modest or no adverse effects on bone mineral density (BMD), whilst dual agonists may confer a relatively higher risk of osteoporosis and fractures, plausibly mediated by greater weight loss magnitude and concomitant reductions in lean body mass (LBM) rather than direct osteotoxicity. Intensified surveillance is warranted in susceptible phenotypes, including older adults and postmenopausal women with low baseline BMD under conditions of rapid weight loss. Osteoporosis risk is further amplified by pre-existing osteopenia, nutritional deficiencies, and concomitant exposure to bone-active agents. Given the limitations of serial dual-energy X-ray absorptiometry (DXA), including cumulative radiation exposure and limited sensitivity to early remodeling changes, biochemical markers potentially depict bone turnover more dynamically. Measurement of dynamic bone resorption markers enables early identification of skeletal disturbances, supporting proactive adjustment of therapeutic strategy, dosing, and duration. Specifically, deoxypyridinoline (DPD), a bone-specific collagen crosslink, is a highly sensitive and rapidly responsive urine biomarker of osteoclastic activity. Incorporating DPD urine testing into monitoring frameworks potentially facilitates individualized therapeutic modulation, optimizing the metabolic efficacy of GLP-1RAs while safeguarding skeletal integrity.
