An open source ultrasonic anemometer for the spatially distributed and time synchronized measurement of large scale flow fields.
Article in HardwareX, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
The quantification of flow speed and -direction is key to many aerodynamic investigations. In case of large scale flow fields and outdoor environments optical techniques such as particle image velocimetry or Shake-the-Box are difficult to implement. Instead, a sufficient amount of point-wise measurements can be employed. Ultrasonic anemometers are a compelling solution due to their high accuracy and low drift even at low to moderate flow velocities. Commercial ultrasonic anemometers often lack a synchronization method and an analog output and most of the available products are closed source and therefore the algorithms employed have unknown characteristics such as time delay, error handling and filtering. The goal of this paper is to develop an ultrasonic anemometer that can measure flow velocities up to 35 m s
