Accuracy of a Novel High-Throughput "Car Blood Pressure" Measurement Protocol.
Article in American journal of hypertension, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundMore than one in three adults with hypertension in the United States are unaware of their condition, highlighting the importance of large-scale screening campaigns. Currently, the identification of hypertension is largely limited to medical settings. To help overcome this barrier, we developed a novel high-throughput screening protocol that measures blood pressure (BP) while patients remain seated in an automobile ("car-BP"). The aim of this study was to provide an initial assessment of the accuracy of car-BP.
methodsThree BP readings were determined in a clinic exam room before and after three BP readings were taken while patients were seated in a parked car outside (n = 100 participants). The same validated device model (Omron HEM-907XL) and BP measurement methods adhering to guidelines were used in both scenarios. The average of all 6 clinic readings was compared to the average of the 3 car-BP readings in each individual.
resultsMean clinic and car-BP readings were 120.9 ± 16.2/78.0 ± 9.9 and 118.9 ± 15.2/76.0 ± 10.0 mm Hg, respectively. The paired mean and absolute mean differences in systolic BP levels between methods were -1.92 mm Hg (95% confidence interval (CI) -3.2 to -0.7 mm Hg) and 4.8 mm Hg (95%CI 3.8 to 5.6 mm Hg), respectively. A total of 85% of participants had both systolic and diastolic BP levels ≤ 10 mm Hg different between measurement scenarios (meeting the a priori determined study primary outcome).
conclusionsCar-BP represents an innovative and accessible approach for potential large-scale hypertension screening campaigns.
