Active head-impulse tests may help detect acute unilateral vestibulopathy: a preliminary study.
Article in Frontiers in neurology, 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
Introduction: Apart from conventional head-impulse tests (i.e., passive HITs), patency of the vestibulo-ocular reflex (VOR) can also be evaluated through self-generated HITs (i.e., active HITs). We aimed to evaluate the usefulness of active (self-generated) HITs in patients with acute unilateral vestibulopathy/vestibular neuritis (AUVP/VN) during the acute stages. Methods: We prospectively recruited 24 patients with AUVP/VN and 30 healthy participants from January 2019 to June 2026. All subjects underwent passive as well as active HITs. We compared the latency and amplitude of corrective saccades during active and passive HITs. Results: During active HITs, patients with AUVP/VN exhibited shorter latency ( Discussion: Detection of short-latency (≤ 242 ms) and large (≥ 8.15°) corrective saccades may help identify AUVP/VN during active HITs. Active HITs may provide complementary information for detecting acute unilateral vestibular hypofunction, although further validation is warranted.
