Anemia and malnutrition in geriatric hospitalized patients: a cross-sectional retrospective study.
Article in BMC geriatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 factors contributing to anemia in older adults are in need of clarification. We investigated associations between nutritional biomarkers and the incidence of anemia.
methodsA cross-sectional study was conducted in two centers. Data were collected from patients living in long-term care hospitals. The Geriatric Nutritional Risk Index (GNRI) was applied to determine nutritional risk. Blood parameters were obtained from medical records. Anemics vs. non-anemics were assigned according to hemoglobin levels following the WHO guidelines. Multiple linear regression analysis were performed for statistical analysis.
resultsThe sample consisted of N = 97 geriatric patients (mean age 84.9 years, 86% female). Anemic patients had a significantly lower GNRI (M = 90.6 ± 5.94; p =.007) than non-anemic patients (M = 94.7 ± 6.11). Serum albumin (p =.008), blood iron (p <.001), number of erythrocytes (p <.001), and the hematocrit value (p <.001) were also significantly lower in patients with anemia. Multiple linear regression showed that serum albumin concentration, in addition to the hematocrit, was the driving factor for hemoglobin concentration in anemic patients (p =.004; R²=0.77).
conclusionThe present study indicates that nutritional risk plays a substantial role in anemia development in older adults. These findings may be attributable to multifactorial metabolic pathways of macro- and micronutrients on blood hemoglobin concentration. Malnourished geriatric patients with anemia may benefit from a diet rich in protein and iron-rich foods.
