Evaluation of ultrasonography and plethysmography in detecting blood loss and volume replacement in a platelet apheresis model.
Article in Heliyon, 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
Background: Rapid, reproducible, and noninvasive diagnostic methods like Ultrasonography (US) and plethysmographic measurements such as the perfusion index (PI) and pleth variablity index (PVI) have great potential value for emergency trauma cases in which blood loss needs to be recognized quickly and accurately. Objectives: We planned this study to evaluate the utility of US, PI, and PVI in detecting early-stage hemorrhage and mimicking volume replacement using a platelet apheresis model. Methods: This prospective, observational study included 46 healthy platelet apheresis volunteers who met inclusion criteria. Both of US measurements of Vena Cava Inferior (VCI Results: Among the total 308 platelet apheresis, 46 male volunteers met inclusion criteria and consented to participate in the study. Of these 46 male volunteers, nine declined to have US measurements. After a mean blood loss of 440 ml in the first phase of apheresis, IVC Conclusion: Per this platelet apheresis model, IVC
