On the Feasibility of Pulse Wave Velocity Imaging for Remote Assessment of Physiological Functions.
Article in Advances in experimental medicine and biology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
introductionPulse wave velocity imaging (PWVi) is a novel technology developed by our group for real-time assessment of ischemia. The objectives of this proof-of-concept study included (1) remote detection of blood flow pulse and (2) assessing the feasibility of pulse wave velocity (PWV) imaging.
methodsPWVi is based on a 12-bit RGB camera (Basler acA-2000-165uc) capturing videos at up to 1000 fps. Videos of the hands of healthy individuals were taken, segmented, and processed to assess pulse wave velocity (PWV) and photoplethysmographic (PPG) signals.
resultsPWV and PPG waveforms were readily collected for multiple segments. The PWVi device performed well, even without an external source of illumination. Mean PWV of 341.3 (±151.0) cm/s was obtained.
conclusionsPWVi is a portable, accessible, and cost-effective technology for assessing physiological parameters remotely.
