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
backgroundPolypharmacy is widespread among older adults with ischemic stroke (IS), which may increase the prevalence of potentially inappropriate medications (PIMs). This study aimed to determine the prevalence and factors associated with PIMs in hospitalized IS patients using the 2019 and 2023 Beers criteria.
methodWe conducted a cross-sectional study by extracting electronic medical records of hospitalized elderly IS patients (aged ≥ 65 years) at Jinshan Hospital of Fudan University from January to December 2021. PIMs were identified based on the 2019 and 2023 Beers criteria. The coherence of the two criteria was evaluated via the kappa test. Poisson regression was performed to identify factors associated with PIM use.
resultsA total of 559 elderly IS patients were included in the study. According to the 2023 Beers criteria, 43.29% of patients used at least one PIM, compared with 38.82% based on the 2019 Beers criteria. The three most frequently identified PIM classes in both versions were antipsychotics, diuretics, and antidepressants. The kappa value was 0.908 (P < 0.001), indicating strong coherence between the two criteria. Female sex, a higher number of prescribed medications, and longer hospital stays were significantly associated with increased PIM use. Across both sets of criteria, the number of prescribed medications was identified as the strongest factor associated with PIM use.
conclusionThe overall prevalence of PIMs was slightly higher according to the 2023 Beers criteria than the 2019 version. PIM use was more prevalent among older female IS inpatients with excessive polypharmacy and hospital stays of 21 days or longer.
