Clot formation and resolution properties of platelets during cold storage for 21 days.
Article in Transfusion, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundCold storage (2-6°C) preserves the aggregatory and clot formation properties of platelets beyond the standard 7-day shelf life. Comparatively little is known about the effect of cold storage on clot resolution functions, which are necessary to ensure normal hemostatic balance is maintained. STUDY DESIGN AND
methodsDouble-dose apheresis platelets (n = 8) were collected using the Trima apheresis platform (40% plasma/60% PAS-E). Platelets were sampled on Day 1 post-collection and allocated to room temperature (RT; 20-24°C) or cold storage (2-6°C). In vitro testing was performed over a 21-day period.
resultsThe coagulation profile of cold-stored platelets was better maintained throughout storage compared to RT platelets. Cold-stored platelets showed increased thrombin generation potential (faster lag time, higher peak, and increased ETP) compared to RT platelets throughout storage. By viscoelastic testing, the IN-test and EX-test clotting times (CT) were maintained over cold storage for 21 days, while the clot strength (MCF) decreased by approximately 15%. The lysis time (LT) was unchanged during cold storage. Macroscopically, less clot retraction and a higher percentage of internal lysis were observed in cold-stored platelets; however, susceptibility to external lysis was not affected.
conclusionHemostasis requires a delicate balance between clot formation and resolution, and we have shown that the key functional properties of cold platelets stored in PAS-E are well-regulated during extended storage for 21 days.
