Practices in platelet production: A Nordic perspective (2018-2022).
Article in Vox sanguinis, 2026. 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
BACKGROUND AND
objectivesThe Nordic region includes Denmark, Finland, Iceland, Norway and Sweden, with a population of >27.5 million. Blood services are managed differently in each country. Current data on platelet concentrate (PC) production methods and capacity are important for developing efficiency and cross-border preparedness. MATERIALS AND
methodsRetrospective data for 2018-2022 were collected through an online survey sent to all blood centres producing platelets in the region. Questions focused on collection procedures (aphaeresis [AP] or whole blood [WB]-derived pools), use of bacterial culture screening (BCS) or pathogen reduction (PR), shelf-life, transfusion practices and quality control.
resultsA total of 43 blood centres provided data (83% response), including complete national coverage for Sweden, Finland and Iceland. Between 2018 and 2022, 632,596 PCs were produced at participating centres. Annual PC production was stable over the period. Most PCs were WB pools (77%). Automated separation to produce interim platelet unit (IPU) pools was performed at 19 centres. PR and BCS were used in 17 and 23 centres, respectively. Shelf-life ranged from 5 days (no safety measure) to 7 days (PR or BCS). The number of PCs transfused in the region declined by ~5% from 2018 to 2022.
conclusionPlatelet production methods, including safety measures to prevent bacterial contamination, varied widely in the Nordic region. Harmonization, including the use of PR or BCS with 7-day storage, may contribute to resilient platelet supplies in the region.
