Gait disorientation as a proxy for impaired spatial navigation: Associations between the Gait Disorientation Test and vestibular-mediated functions.

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
introductionDizziness and imbalance from vestibular dysfunction may lead to gait disorientation and impaired construction of mental maps needed for spatial navigation. The Gait Disorientation Test (GDT), consisting of two components, walking eyes open (WEO) and walking eyes closed (WEC), can identify gait disorientation. We aimed to examine associations between the GDT and measures that reflect aspects of spatial navigation.
methods40 adults (20 with vestibular hypofunction, 20 controls) recruited from the community completed the GDT, Sensory Organization Test (SOT), Activities-specific Balance Confidence Scale, Dizziness Handicap Inventory, dynamic visual acuity testing, and the 5-Times-Sit-to-Stand Test. The composite score (COMP) and sensory analysis scores for somatosensory (SOM), vision (VIS), vestibular (VEST), and vision preference (PREF) were calculated for the SOT.
resultsThe GDT was associated with the COMP (p < 0.001), VIS (p < 0.001), VEST (p = 0.001), and PREF (p = 0.021) but not the SOM (p = 0.223) scores. WEO was associated with VIS (-0.35 [-0.59, -0.04], p = 0.028), VEST (-0.32 [-0.57, -0.01], p = 0.046), and the COMP score (-0.44 [-0.66, -0.14], p = 0.005). WEC was associated with VIS (-0.73 [-0.85, -0.55], p < 0.001), VEST (-0.52 [-0.71, -0.24], p = 0.001), PREF (-0.37 [-0.61, -0.07], p = 0.018), and the COMP score (-0.75 [-0.86, -0.57], p < 0.001). DISCUSSION: Greater gait disorientation on the GDT is moderately to strongly associated with balance in challenging sensory conditions. Stronger associations with WEC likely reflect the importance of the vestibular system for spatial navigation. Performance on the GDT might be viewed as a proxy for spatial navigation ability.
