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: Insulin therapy is crucial for Type 1 and advanced Type 2 diabetes management. Despite the convenience of insulin pens, improper use persists due to limited patient education. Pharmacists' expertise in counseling and medication safety uniquely positions them to address these gaps through individualized guidance on use, adherence, and monitoring. Objectives: This study aimed to evaluate the impact of pharmacist-led interventions on improving insulin injection practices among diabetes patients. Methods: A pre-post interventional study was conducted at Dhulikhel Hospital (April-September 2018) among 81 consecutively enrolled insulin pen users (≥12 years; on pens ≥2 weeks) from inpatient and outpatient wards. Patients underwent baseline assessment of 16 injection technique elements, received one-to-one pharmacist-led training with demonstration, and were reassessed immediately and after 2 weeks. The primary outcome was the total technique score (0-16), analyzed using Friedman's test and Wilcoxon signed-rank test. Results: Cold chain maintenance was suboptimal, with 51.9 % of patients transporting insulin cartridges without an icepack. Unsafe needle disposal was common, with 40.7 % discarding needles in municipal vehicles, 13.6 % in bushes, and 4.9 % in rivers. Pharmacist-led interventions significantly improved all practices ( Conclusion: Pharmacist-led education significantly improved insulin injection techniques. Integrating pharmacists into routine diabetes care and reinforcing education is essential to sustain these improvements. These findings underscore that clinical pharmacy interventions make a tangible difference in improving healthcare outcomes.
