The impact of storage time on coagulation factor activity in FFP.
Article in Frontiers in medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: This research aims to explore the change law of coagulation factor activity in fresh frozen plasma (FFP) with storage time under standard storage conditions, evaluate the quality change characteristics during its validity period, and provide scientific basis for optimizing the inventory management and turnover strategy of fresh frozen plasma in primary hospitals. Methods: FFP under standard storage conditions (≤-18 °C) was followed up for 1 year (from the date of collection), and the activated partial thromboplastin time (APTT), prothrombin time (PT), international normalized ratio (INR) and factor VIII (FVIII) activity at different time points were measured, and the results were analyzed statistically. Results: The PT and APTT of FFP showed an upward trend with the extension of storage time, and remained within the normal reference range, but the growth rate of PT increased after more than 300 days. The activity of FVIII decreased by 19.35% compared with the baseline level, and the qualified rate was only 72% after 120 days of storage. Conclusion: Under standard storage conditions, the coagulation function indexes (PT, APTT) of FFP remain normal, but the activity of some coagulation factors (such as FVIII) will decrease significantly with the extension of storage time and inventory management of fresh frozen plasma that been stored nearly 300 days should be enhanced.
