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: This study identified the relationships between health literacy, self-efficacy, and medication adherence among older people with polypharmacy and analyzed the factors affecting medication adherence. Methods: This was a cross-sectional study using a survey of 95 participants who were on five or more drugs, 65 years or older, and visited one community center in Seoul between August 5, 2019 and August 7, 2019. Data were collected using a questionnaire and analyzed with descriptive statistics, t-test, ANOVA, Tukey test, Pearson's correlation coefficient, and multiple regression via the IBM SPSS 23.0 program. Results: The participants took on average 8.32±3.90 drugs daily. Their health literacy was very low at 3.53±2.07. Self-efficacy and medication adherence were high at 33.63±5.36 and 15.03±3.27, respectively. Health literacy differed based on age and education levels, whereas self-efficacy differed depending on the frequency of medication. No demographic or medication-related factors caused a difference in medication adherence. Health literacy did not correlate with self-efficacy and medication adherence. Self-efficacy showed a negative correlation with medication adherence (r=-.52, Conclusion: Medication adherence was generally high, with self-efficacy being the main influencing factor. Hence, intervention programs that promote self-efficacy should be implemented for older people with polypharmacy.
