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: Blood is an irreplaceable medical resource, yet blood unit discard remains a significant challenge for transfusion services. This study aimed to evaluate discard rates by integrating both infectious (TTI) and non-infectious causes and identifying factors associated with blood wastage to provide evidence to support strategies for improving blood safety. Methods: An institutional-based retrospective cross-sectional study was conducted using data from 2022 to 2025 across Dessie, Kemise, Woldia, and Sekota Blood Banks. Data were extracted from Blood Bank databases using a structured checklist and analyzed with SPSS version 26.0. Both univariable and Multivariable logistic regression were performed to identify predictors of transfusion transmissible infections (TTIs) and non-infectious causes, with statistical significance set at Results: Records from 60,008 donors and 67,976 blood products were reviewed. A total of 6,130 units (9.02%) were discarded. TTIs accounted for 4.6% of discards, led by Hepatitis B virus (2.0%) and Syphilis (1.2%). Non-infectious causes contributed 4.4%, primarily due to expiration (2.0%). ABO group, Rh factor, donor age, donor type, collection site, and Blood Bank location were identified as significant predictors of discard. Conclusion: The study reveals a notable blood unit discard rate of 9.02%, driven equally by infectious transfusion-transmissible infections and non-infectious factors like expiration. Key risk factors include donor demographics, blood group, and specific blood bank locations, highlighting the need for better inventory management and targeted donor selection.
