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
A novel method for measuring non-axial flow speed using optical techniques such as optical coherence tomography is introduced. The approach was based on the use of a modally-specific photonic lantern, which permits simultaneous probing of the sample with three distinct coherent spread functions. Transverse flow speed is measured from the ratio between the cross-correlation and autocorrelation of the signals. It achieved a 3 to 5 times higher accuracy than common autocorrelation approaches and measured flows as slow as 0.5 mm/s for an integration time of 1 second. Additionally, the method gives information on the flow's three-dimensional orientation, does not require information about the diffusion coefficient, and is more robust to bias errors such as a gradient in the axial flow velocity.
