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
backgroundCognitive frailty (CF), defined as the coexistence of physical frailty and cognitive impairment in the absence of dementia, is common among older adults with diabetes.
aimsThis study investigated associations of metformin use and nutritional status with CF, cognitive impairment, and physical frailty among older adults with type 2 diabetes.
methodsThis cross-sectional study was conducted at the geriatric outpatient clinic of a tertiary care hospital. CF was defined as the coexistence of cognitive impairment (Montreal Cognitive Assessment (MoCA) ≤ 25 points) and physical frailty (FRAIL score ≥ 3 points). Nutritional status was measured using the MNA-SF. Hierarchical multivariable logistic regression models were constructed to assess the independent associations of metformin use and nutritional status with CF, cognitive impairment, and physical frailty, progressively adjusting for age, sex, BMI, education level, vitamin B12 level, eGFR, polypharmacy, HbA1c level, PPI use, and insulin use.
resultsA total of 468 older adults with diabetes were included, median age 70 years (IQR:66-75), 70.3% of the participants were female. Based on clinical assessments, 9.6% were classified as having CF, 18.8% as having physical frailty only, and 9.6% as having cognitive impairment alone. Logistic regression analysis indicated that metformin use and being well-nourished were significantly associated with lower odds of CF (OR[95%CI]: 0.275 [0.160-0.620], p = 0.002; and 0.150 [0.118-0.245], p < 0.001, respectively). Similar associations were observed for cognitive impairment and physical frailty.
conclusionsMetformin use and optimal nutritional status were independently associated with lower odds of cognitive frailty, cognitive impairment, and physical frailty, suggesting that these modifiable factors might contribute to better outcomes in geriatric diabetes care.
