Influence of eye dominance on objective and subjective excyclotorsion in unilateral superior oblique muscle palsy: objective cyclotorsion measured by fundus photography.
Article in Japanese journal of ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeTo study the effect of eye dominance on excyclotorsion in unilateral superior oblique palsy (USOP). STUDY
designRetrospective clinical study
methodsObjective excyclotorsion was measured as the disc-to-fovea angle by fundus photography OU. Subjective excyclotorsion was determined with a major amblyoscope based on the difference in the earth vertical and subjective visual vertical. Eye dominance was determined by the hole-in-the-card method. A p-value ≤ 0.05 was considered statistically significant. SUBJECTS: Data of 24 USOP patients were retrospectively collected. The diagnosis was mainly made by the Parks 3-step method, history and the presence of characteristic excyclotorsion. When possible, orbital magnetic resonance imaging findings were obtained.
resultsThe median angle of objective excyclotorsion in the paretic eyes was significantly larger than in the nonparetic eyes. Both median angles of objective/subjective excyclotorsion in the dominant eye were significantly smaller than those of the non-dominant eye. Patients were subdivided into two groups: group A, those whose paretic eye was the dominant eye (n = 13); group B, those whose paretic eye was the non-dominant eye (n = 11). The objective/subjective excyclotorsional angles of the paretic eye were significantly larger than of the non-paretic eye only in group B.
conclusionIn USOP the angle of excyclotorsion in the dominant eye is smaller than in the non-dominant eye. This may imply that the vertical sense of visual space is mainly adapted to the dominant eye, keeping the subjective vertical close to the earth vertical.
