Prevalence and determinants of micronutrient deficiencies in malnourished older hospitalized patients.
Observational study in The journal of nutrition, health & aging, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
BACKGROUND AND
objectiveMalnutrition and micronutrient deficiencies represent significant concerns in geriatric care, leading to adverse health outcomes in older adults. The study aimed to investigate the prevalence and determinants of micronutrient deficiencies in malnourished older hospitalized patients. DESIGN AND
settingThis prospective, observational study was conducted in a geriatric acute care unit.
participantsThe study included 156 malnourished older adults. MEASUREMENTS: Malnutrition was identified using the Mini Nutritional Assessment-Short Form. Micronutrient status was assessed through serum analysis of vitamins (A, B1, B6, B12, C, D, E, H, K, folic acid) and minerals (iron, zinc, copper, selenium) within 24 h post-admission.
resultsThe average patient age was 82.3 ± 7.5 years, with 69% female. The results revealed a high prevalence of micronutrient deficiencies, with 90% of patients exhibiting deficiencies in three or more micronutrients. Notably, every patient presented at least one micronutrient deficiency. Common deficiencies were found in vitamins C (75%), D (65%), H (61%), and K (45%), as well as folic acid (37%), iron (31%), zinc (36%) and selenium (35%). In binary regression analysis, the amount of previous weight loss was significantly associated with a higher prevalence of multiple (>2) micronutrient deficiencies (P = 0.045). Other variables such age (P = 0.449), gender (P = 0.252), BMI (P = 0.265) and MNA-SF score (P = 0.200) did not show any significant association with the prevalence multiple micronutrient deficiencies.
conclusionThe high prevalence of micronutrient deficiencies in malnourished older hospitalized patients underscore the urgent need for targeted interventions to address micronutrient deficiencies in this population, promoting their health status.
