Clinical observations from the clinical video head pulse test in patients with idiopathic horizontal semicircular canal light cupula.

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
Objective: The objective of the study is to analyze and explore the characteristics of the video head impulse test (vHIT) for light cupula in the idiopathic horizontal semicircular canal and compare them with those of horizontal semicircular canal cupulolithiasis (HC-cu) in order to investigate the potential mechanism involved. Methods: Data from 51 cases of idiopathic light cupula and 42 cases of horizontal semicircular canal cupulolithiasis were retrospectively analyzed. The positional nystagmus features, vHIT anomaly rate, gain value, saccades, and other indicators were compared. SPSS 26 and Medcalc 22 were used to analyze the differences and correlations. Results: There were no differences in sex, age, the affected side, and positional nystagmus between the light cupula group and HC-cu group ( Conclusion: The vHIT results of idiopathic HC light cupula and HC-Cu were different as they are distinct diseases. Light cupula may be associated with some mild lesions in the vestibulo-ocular reflex (VOR) pathway. The lighter cupula theory is the possible mechanism.
