Study on the association between dietary inflammatory index and sarcopenia in older adults.
Article in BMC geriatrics, 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
objectiveTo investigate the association between the Dietary Inflammation Index (DII) and sarcopenia in older adults, providing theoretical support for clinical prevention and treatment.
methodsElderly individuals aged 60 years and older in Urumqi were selected. Data were collected through questionnaires and physical examinations to assess sarcopenia prevalence. Logistic regression analyzed the relationship between DII and sarcopenia. A stepwise logistic regression model incorporating age, BMI, waist circumference, DII, and PSQI total score was constructed for prediction.
resultsEach 1-unit increase in DII significantly elevated sarcopenia risk (OR = 2.02, 95% CI: 1.49 to 2.73). The predictive model demonstrated good discrimination (AUC = 0.736 in training set, AUC = 0.742 in testing set) and calibration (Hosmer-Lemeshow test P > 0.05). Decision curve analysis indicated significant clinical net benefit within the 15% to 45% risk threshold range.
conclusionElevated dietary inflammation index represents an independent risk factor for sarcopenia in older adults. The multifactorial prediction model demonstrates robust discriminatory capability and clinical utility. Optimizing dietary patterns to reduce DII is recommended for sarcopenia prevention.
