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: To describe the status of home medication behaviors and medication literacy among older patients with chronic diseases in China and to identify factors influencing medication literacy levels to inform improvement strategies. Patients and Methods: A national cross-sectional study was conducted from October 2022 to the end of June 2023 across 31 provinces using a multi-center, quota-based convenience sampling approach. Trained pharmacists collected data via face-to-face interviews using a validated Knowledge, Attitude, and Practice (KAP) questionnaire. Medication literacy was dichotomized into adequate (score ≥186) and inadequate (<186). Multivariable logistic regression was employed to identify associated determinants. Results: Among the 10,363 eligible participants, 48.31% demonstrated adequate medication literacy. Prevalent suboptimal home medication behaviors were observed: 57.05% failed to completely retain original medication packaging, and 74.25% could not fully understand package inserts. Through multivariable logistic regression, several key factors were identified as significant predictors of medication literacy. Higher educational attainment (college degree and above: OR = 2.185, 95% CI: 1.744 to 2.738) was identified as a strong predictor of adequate literacy. Conversely, discarding medication package inserts (OR = 0.697, 95% CI: 0.588 to 0.828) and the inability to comprehend package inserts (OR = 0.265, 95% CI: 0.226 to 0.311) were found to be negatively associated with literacy levels. Furthermore, 93.60% of the cohort reported the presence of somatic symptoms, which were frequently misattributed to normal aging rather than potentially modifiable medication-related causes. Conclusion: Medication literacy among older Chinese adults with chronic diseases remains suboptimal, with nearly half failing to achieve adequate levels. Independent self-management is significantly associated with socioeconomic factors and specific behavioral gaps. A home-based pharmaceutical care system should be implemented to prioritize vulnerable groups, advocate for the retention of original packaging, and promote the development of simplified medication instructions.
