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
The use of generic medicines (GEs) is being promoted to reduce healthcare costs. This study aims to evaluate the effect of a pharmacist-led educational intervention on the number of patients switching from brand-name medicines to GEs among patients who preferred brand-name products. Pharmacists provided a standardized explanation using pamphlets about GEs to patients who wished to use brand-name medicines and allocated time to answer questions. Basic knowledge about GEs (nine items) and perceptions of GE use (three items) were assessed before and after the intervention to determine whether changes influenced switching behavior. Between 1 March and 30 July 2025, 40 patients were enrolled in the analysis. Following the intervention, the number of patients using one or more brand-name medicines significantly decreased to 25. Knowledge and perceptions of GEs significantly increased after the intervention and were associated with an increased rate of switching to GEs. Binominal logistic regression analysis identified age ≥ 65 years as a strong factor associated with preference for brand-name medicines (OR, 16.45; 95% CI, 1.48-182.65;
