Nutritional Status in a Contemporary Urban Population-Based Cohort: Prevalence, Clinical Associations and Long-Term Health Outcomes.
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
backgroundNutritional deficiencies are associated with poor prognosis in a wide range of illnesses. However, the prognostic impact of poor nutritional status with respect to long-term all-cause mortality in the general non-diseased population is not well described.
objectivesThis study sought to report the prevalence, clinical associations, and prognostic consequences of poor nutritional status in a contemporary urban population in Germany.
methodsA cohort of 8398 participants from the LIFE-Adult Study was enrolled. Four objective nutritional scores, the Prognostic Nutritional Index (PNI), the Controlling Nutritional Status Score (CONUT), the Nutritional Risk Index (NRI), and the Triglyceride Cholesterol Body Weight Index (TCBI), were calculated at baseline, and participants' nutritional status was classified according to score tertiles. The relationship between nutritional status and common risk factors as well as major diseases was assessed. In addition, the association between poor nutritional status at baseline and the risk of all-cause mortality during a seven-year follow-up period was examined.
resultsAccording to the WHO definition of obesity, the LIFE-Adult Study cohort was, on average, overweight, with almost two-thirds of participants (67%) having a BMI ≥ 25 and only 1% being underweight. However, poor nutritional status was not associated with a specific BMI category. Higher age, female sex, cancer, and chronic kidney disease were more common, whereas active smoking and hypercholesterolemia were less prevalent among participants in the lowest PNI tertile (
conclusionsPoor nutritional status is associated with increased mortality in the general population. Clinical trials are needed to prospectively evaluate the efficacy of nutritional interventions on health outcomes.
