Changes in central and peripheral hemodynamic parameters during blood donation.

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: Blood donation is a common procedure, yet its acute effects on central and peripheral hemodynamics are not fully understood. This study aimed to systematically quantify immediate cardiovascular changes induced by whole blood donation in healthy adults, with a primary focus on arterial pressure and central hemodynamic parameters. Methods: Thirty healthy volunteers (12 female, 18 male; median age 34 years, IQR 24-53) underwent standardized whole blood donation. Non-invasive measurements of central and peripheral hemodynamics were performed immediately before and after donation using the VascAssist 2 device, enabling assessment of brachial and aortic blood pressures, heart rate, augmentation index (AIx), pulse wave velocity (PWV), and left ventricular ejection time (LVET). Results: Blood donation resulted in a significant reduction in brachial systolic blood pressure (SBP) [pre: 131 mmHg [IQR 121-138] vs. post: 127 mmHg [IQR 116-134]; median change -4mmHg, IQR -10 to 0; Conclusion: Acute whole blood donation induces a mild but statistically significant decrease in peripheral SBP, accompanied by reductions in AIx and LVET, while central aortic blood pressure and vascular stiffness remain unchanged. These findings indicate that healthy individuals exhibit immediate adaptive mechanisms that preserve central cardiovascular stability in response to mild volume depletion. The results support the overall hemodynamic tolerability of blood donation and provide insight into the transient vascular and cardiac adaptations elicited by acute blood loss.
