Macroscopic handling stability of platelet-rich fibrin under short-term temperature variations: a prospective experimental study.
Article in Oral and maxillofacial surgery, 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
backgroundThis prospective experimental study evaluated whether short-term post-centrifugation handling under different environmental temperature conditions influences the macroscopic characteristics of platelet-rich fibrin (PRF) during routine clinical preparation. MATERIALS AND
methodsVenous blood samples were obtained from 38 healthy volunteers and processed using a standardized centrifugation protocol (3000 rpm, 10 min). PRF clots were harvested immediately after centrifugation or following 3 min of storage at room temperature (+ 20-22 °C) or + 4 °C. Macroscopic parameters, including clot weight, clot volume, membrane surface area, and membrane volume, were measured and compared.
resultsNo statistically significant differences were observed among the three handling conditions for any of the measured macroscopic parameters (p > 0.05). However, donor-related factors influenced PRF dimensions. Female participants exhibited significantly greater clot weight and clot volume than males under all conditions, while increasing age was positively correlated with clot weight and volume in the room-temperature and + 4 °C groups (p < 0.05).
conclusionsShort-term post-centrifugation storage of PRF at room temperature or + 4 °C was not associated with statistically significant differences in its measured macroscopic characteristics. Future studies evaluating cellular viability, growth-factor release, fibrin architecture, mechanical properties, and biological activity are needed to complement these macroscopic findings.
