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: Previous studies have linked polypharmacy with nutritional and psychological vulnerability in older adults, but their concurrent presentation in routine outpatient care remains incompletely characterized. This exploratory study examined nutritional status and depressive symptom burden according to polypharmacy status among older adults attending outpatient clinics at a public hospital. Patients and Methods: This exploratory cross-sectional observational study included 28 community-dwelling adults aged 65 years or older attending rehabilitation medicine or family medicine outpatient clinics at a single public hospital in Seoul, Republic of Korea. Polypharmacy was defined as the regular use of five or more physician-prescribed medications. Nutritional status was assessed using the full Mini Nutritional Assessment (MNA), and depressive symptoms were assessed using the interviewer-administered Korean 15-item Short Form Geriatric Depression Scale (SGDS). Continuous variables were compared using Mann-Whitney Results: Polypharmacy was present in 8 participants (28.6%). Compared with participants without polypharmacy, those with polypharmacy had lower MNA scores (median [IQR], 21.25 [20.25-22.13] vs 24.25 [23.25-26.00]; p=0.005), more frequent nutritional risk or malnutrition (100.0% vs 35.0%; p=0.002), higher SGDS scores (8.00 [4.75-9.25] vs 3.00 [2.00-6.00]; p=0.024), and smaller calf circumference (31.50 [30.38-33.90] vs 35.25 [33.45-36.63] cm; p=0.042). The prevalence of depressive symptoms defined by SGDS ≥8 did not differ significantly (62.5% vs 20.0%; p=0.068). Conclusion: In this small exploratory sample, polypharmacy co-occurred with poorer nutritional status and greater depressive symptom burden. These unadjusted findings are hypothesis-generating and do not establish that polypharmacy causes poorer nutritional status or depressive symptoms. Larger prospective studies with adequate adjustment for multimorbidity and other potential confounders are needed.
