Drug Burden Index and its association with postural balance and falls among community-dwelling older adults.
Article in Frontiers in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Polypharmacy is linked to balance impairment and falls. Thus, pharmacological screening tools are essential for identifying high-risk patients. Objectives: To investigate the association between medication burden, postural balance, and recent falls in community-dwelling older adults. Methods: This cross-sectional study included adults aged ≥ 60 years attending a university outpatient clinic in Brazil. Sociodemographic characteristics, comorbidities, medication use, handgrip strength, and recent fall were collected. Medication burden was classified as no, low, or high according to the Drug Burden Index. Postural balance was assessed using a standardized one-legged stance protocol on a BIOMEC 400-412 force platform, with Center of Pressure (COP) area and sway velocity as primary and recent falls as secondary outcomes. Results: This study included 170 participants, and no demographic differences were found across DBI categories. DBI was significantly associated with postural balance, with greater COP area and sway velocity among individuals with low or high burden ( Conclusion: Higher DBI was associated with impaired balance and increased fall risk, with a 0.5 cut-off effectively identifying balance impairment and supporting DBI as a practical tool for detecting older adults at risk.
