Factors associated with malnutrition in nursing home residents: A systematic review and meta-analysis of observational studies.
Review in Journal of Korean gerontological nursing, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Purpose: We investigated factors associated with malnutrition in nursing home residents and estimated pooled effect sizes of those associations. Methods: We report this study according to the PRISMA checklist 2020. After registering the protocol, we conducted a systematic search using the keywords "malnutrition," "nursing home," and "factor" on PubMed, EMBASE, CINAHL, and Scopus and conducted a hand search of relevant sources in November 2023. We conducted the meta-analysis using R4.3.1 software. Results: We included 46 studies and entered 35 studies into the meta-analysis. Meta-analysis results showed that (1) demographic factors included being female: pooled odds ratio (pOR) 1.38 (95% confidence interval [95% CI], 1.29~1.47) and higher body mass index: pOR 0.74 (95% CI, 0.66~0.83); (2) health functional factors including dependence with activities of daily living: pOR 3.70 (95% CI, 2.97~4.60) and being immobile: pOR 2.50 (95% CI, 1.39~4.47); (3) eating and oral intake factors including: eating <50% of offered food portions: pOR 3.56 (95% CI, 2.05~6.19) and loss of appetite: pOR 3.60 (95% CI, 1.36~9.57); (4) disease-related factors including dementia: pOR 1.98 (95% CI, 1.59~2.46), depression: pOR 1.84 (95% CI, 1.18~2.85), diabetes: pOR 0.76 (95% CI, 0.58~0.99), and pressure ulcers: pOR 2.14 (95% CI, 1.54~2.97); and (5) medication-related factors such as taking polypharmacy pOR 1.75 (95% CI, 1.24~2.47) were found to have a significant association with malnutrition in nursing homes. Conclusion: These results contribute to updating knowledge about factors associated with malnutrition in nursing homes. Results supported that demographic status, health function, eating and oral intake, and disease, and medication factors significantly aligned with malnutrition. Study results contribute to improving nutritional care in nursing homes and long-term-care settings.
