Risk factors for a central-to-peripheral arterial blood pressure gradient in adults: a systematic review.

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
purposeAccurate hemodynamic monitoring is essential for personalized care in surgical and intensive care unit (ICU) settings, and radial artery catheters are the gold standard. Nevertheless, central-to-peripheral arterial blood pressure gradients (CPAPGs) have been reported in up to 77% of patients, potentially leading to misinformed clinical decisions. Identifying patients at risk of CPAPGs is crucial to adapt monitoring strategies. We aimed to identify the risk factors contributing to CPAPGs and assess their level of consensus in a systematic review of the literature.
methodsFor this systematic review, we searched MEDLINE/PubMed®, Embase, and Cochrane databases (CENTRAL and Database of Systematic Reviews) from inception to 15 July 2024. Studies on adult patients with simultaneous radial and central arterial pressure monitoring were included. We extracted and analyzed risk factors and assessed the consistency of the literature for each.
resultsFrom 741 retrieved articles, we included 55 studies (N = 5,598) evaluating the presence of CPAPGs during cardiopulmonary bypass, hepatic transplant, ICU stay, and other settings. Overall, 90 unique potential risk factors were evaluated, with 36 showing a statistically significant association with CPAPGs. Complex procedures and smaller radial artery diameter were the most consistent predictors, with both showing significant association with CPAPGs in the 3 studies evaluating them. Vasopressor usage showed statistical significance in half the studies evaluating it, and demographic factors, potentially associated with smaller radial artery diameter, such as older age, shorter stature, and female sex, were also statistically significant risk factors in some studies.
conclusionsThe present systematic review identified numerous risk factors for CPAPGs. In patients with multiple contributing factors, clinicians should consider using more central arterial cannulation to minimize the risk of inaccurate pressure measurements.
