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
backgroundIt is an undeniable fact that older adults constitute a particularly vulnerable segment of society, facing an elevated risk of both malnutrition and food insecurity. These are two important problems that impact their general health, in addition to their dietary status. Additionally, food insecurity and malnutrition can affect compliance with the Mediterranean diet.
aimThis study aims to examine the relationship between malnutrition (assessed using the Mini Nutritional Assessment-Short Form, MNA-SF), food insecurity (assessed using the Household Food Insecurity Access Scale, HFIAS), and adherence to the Mediterranean diet (assessed using the Mediterranean Diet Adherence Screener, MEDAS) in community-dwelling older adults.
methods1072 community-dwelling older adults participated in this cross-sectional study. Demographic characteristics of the individuals were questioned with the help of a questionnaire. Malnutrition status, food insecurity and compliance with the Mediterranean diet were assessed with questionnaires.
resultsThe mean age of the participants was 71.5 ± 6.0 years, with 55.3% being female. According to the results of the study, 26.5% of the individuals were found to be at risk of malnutrition, and 4.0% were malnourished. 15% of individuals were food insecure and 54.6% were in compliance with the Mediterranean diet. Linear regression analysis was performed to assess the factors influencing the MNA-SF score. The model, which assessed the impact of gender, age, education level, income status, body mass index (BMI), and HFIAS score on MNA-SF, was found to be significant (R²=0.419; p < 0.001). A negative significant correlation was found between the HFIAS score and education level, income status, number of main meals and snacks (p < 0.05). However, no statistically significant correlation was found between the MEDAS score and HFIAS score and MNA-SF score (p > 0.05).
conclusionIn conclusion, there is a significant relationship between food insecurity and malnutrition. Developing strategies and taking precautions regarding food insecurity in the older adult group, which is quite fragile, may be effective in reducing the prevalence of malnutrition.
