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: Central sterile supply departments (CSSDs) play a critical role in surgical patient safety by ensuring the effective cleaning and correct packaging of reusable surgical instruments. However, process defects may still occur and lead to rework, delays, or safety risks. This study evaluated the effectiveness of a closed-loop defect management improvement program for surgical instrument reprocessing in a CSSD. Methods: We conducted a retrospective quasi-experimental before-after study comparing pre-intervention (January-June 2025, conventional management) and post-intervention (July-December 2025, closed-loop defect management improvement model) periods at West China Hospital. Data were collected through routine operational audits performed by trained human observers, including visual inspection, ATP testing, and protein residue testing, according to departmental standards. The intervention included standardized defect recording, structured analysis, corrective actions, feedback, and targeted training. Outcomes included qualified rates of cleaning and packaging, along with assembly errors, label errors, packaging integrity violations, and instrument damage. Results: In 2025, 54,412 cleaned instruments and 6,488 packages were randomly inspected. Packaging tracking covered 215,927 packages (107,943 pre-intervention; 107,984 post-intervention). Compared with the pre-intervention period, the qualified rate of regular sampling tests increased from 97.99% to 99.76% ( Conclusion: In the CSSD, implementing the closed-loop defect management improvement model was associated with improved reprocessing quality and reduced packaging-related defects. Given that our pre-intervention quality rates already exceeded many published figures, we sought to determine whether implementing a closed-loop defect management improvement program could further reduce defect events and enhance reprocessing reliability, rather than merely meeting minimum standards.
