Efficient saccade enhances performance in clinical dynamic visual acuity test.
Article in Frontiers in neuroscience, 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
Purpose: To investigate the eye movement pattern across different speeds during clinical dynamic visual acuity (DVA) tests and their relationship with dynamic visual performance. Methods: Twenty young adults with normal or corrected-to-normal visual acuity underwent clinical DVA tests at 20, 40, 60, and 80 degrees per second (dps). Eye movement was recorded using a table-mounted eye tracker. Smooth pursuit- and saccade-related parameters were calculated from the gaze trace, and the relationships between eye movement parameters and dynamic visual performance were analyzed. Results: DVA was significantly better at 20 dps than at higher speeds ( Conclusion: Eye movement strategies adapt dynamically to target speed. Quick and efficient saccades support improved dynamic visual performance, although high-amplitude saccades and pursuit velocity disrupted tracking at high speeds. These findings offer insights for optimizing clinical DVA tests and enhancing the clinical utility of DVA as a functional vision indicator.
