Interaction between white coat effect and hypertension on arterial stiffness.
Article in Journal of hypertension, 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
objectiveWhite coat effect (WCE) is a debated risk factor for cardiovascular diseases (CVD), and the current findings regarding its association with arterial stiffness in hypertension remain inconsistent. This study aimed to explore the interaction between WCE and hypertension on arterial stiffness.
methodsA total of 7584 participants, including 4679 controls and 2905 individuals with hypertension were enrolled and divided into four groups: control, white coat hypertension (WCH), hypertension, and white coat uncontrolled hypertension (WUCH). Arterial stiffness was assessed using arterial velocity pulse index (AVI) and arterial pressure volume index (API), measured through cuff oscillometry. Logistic regression was used to analyze the risk factors for high CVD risk. The association between API and pulse pressure (PP) was analyzed using restrictive cubic spline (RCS) analysis.
resultsParticipants with WUCH were older than those with WCH (63 vs. 58 years, p < 0.05), had higher PP (73 vs. 62 mmHg, P < 0.05), and a higher API (36 vs. 32, P < 0.05). In multivariable analysis, WCH/WUCH remained a determinant of API. After adjusting for confounding factors, API ( β = 1.046, P < 0.001), and WCH/WUCH ( β = 1.628, P < 0.001) were identified as independent influencing factors for high CVD risk. The RCS analysis of API and PP demonstrated a significant J-shaped relationship.
conclusionsIndividuals with the WCE showed greater peripheral arterial stiffness, especially among women. A J-shaped relationship between API and PP was observed in both WCE and non-WCE individuals. WCE was independently associated with a higher CVD risk.
