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: CT-P17 (Yuflyma), a biosimilar to adalimumab (Humira), offers a cost-effective alternative with improved access for individuals with immune-mediated inflammatory diseases (IMIDs). Assessing patient experience with autoinjector usability and comfort is crucial for ensuring adherence and satisfaction. This study is the first to evaluate patient-reported satisfaction and safety of CT-P17 specifically in people with Crohn's disease (CD). Aims: To evaluate patient satisfaction and safety of CT-P17 in CD. Methods: This cross-sectional study included 15 adults (median age 39.9 years) with CD from two Australian hospitals. All participants had prior experience with biologic therapy and used an autoinjector. Patients had either transitioned from adalimumab to CT-P17 or had been receiving CT-P17 for at least 4 weeks. Data collected included baseline demographics, the Harvey Bradshaw Index (HBI), and the Self-Injection Assessment Questionnaire (SIAQ), a validated instrument assessing patient experience, confidence, and satisfaction with self-injection. SIAQ domain scores ranged from 0 (worst) to 10 (best), with higher scores indicating more positive self-injection experiences. Results: SIAQ scores indicated positive patient experiences. Mean (SD) scores showed high comfort (8.33 ± 1.67), strong self-confidence (8.38 ± 1.53), positive self-image (9.00 ± 2.64), minimal pain/skin reactions (9.22 ± 0.93), and ease of use (8.80 ± 1.89). Overall satisfaction was high (8.76 ± 1.38). HBI scores remained low (mean 0.7), indicating stable disease control. Conclusions: CT-P17 is well-tolerated in CD patients, with high satisfaction and minimal injection discomfort. Its ergonomic autoinjector design supports ease of use. While larger studies are needed, these findings support the broader adoption of adalimumab biosimilars to enhance patient autonomy and reduce healthcare costs.
