HMB-Containing Oral Nutritional Supplementation and Mortality After Hip Fracture in Malnourished Older Adults: A Formulation-Specific Subanalysis of a Prospective Cohort.
Article in Nutrients, 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
backgroundOral nutritional supplementation (ONS) is commonly prescribed in malnourished older adults after hip fracture, but formulations are heterogeneous, and their comparative association with mortality remains unclear. We aimed to evaluate whether HMB-containing ONS was associated with lower mortality than non-HMB ONS and to explore whether supplement formulation combined with treatment persistence was associated with differential mortality patterns.
methodsThis was a formulation-specific subanalysis of a previously described prospective cohort of older adults with hip fracture and malnutrition or significant nutritional risk. Only patients with known ONS formulation were included (
resultsOverall mortality was 14.0% at 3 months, 23.4% at 6 months, and 29.9% at 12 months. At 6 months, mortality was lower among patients receiving HMB-containing ONS than among those receiving non-HMB ONS (13.6% vs. 35.4%;
conclusionsIn this formulation-specific subanalysis of malnourished older adults with hip fracture, an association between HMB-containing ONS and lower 6-month mortality was observed compared with non-HMB ONS. Exploratory findings suggested a clinically relevant mortality gradient according to both supplement formulation and treatment persistence, although these results should be interpreted cautiously. Larger prospective studies are warranted to confirm these findings.
