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: To analyse the subjective visual vertical (SVV) in migraine patients with balance disorders and its correlation with symptoms. We hypothesise that vestibular imbalance reflects a global migraine activation leading to symptom prevalence on one side. Methods: Twenty-six migraine patients with vertigo and/or dizziness (Group A) were studied in the interictal period. Symptoms assessed: unilateral (U) vs bilateral (B) headache (H), cranial autonomic (CAS) or cochlear symptoms (CS), vertigo/dizziness. SVV test was performed in all participants. Group A was compared to Group B (migraine without vertigo/dizziness) and Group C (controls). Main parameters: SVV0 (mean tilt in 6 trials) and SVV side exclusivity (SE: tilt of same sign in ≥ 5 trials). Results: SVV0A (0.80 ± 0.68) was significantly greater than SVV0B (0.39 ± 0.40; p = 0.01) and SVV0C (0.32 ± 0.19; p = 0.001). SVV SE was found in 78.6% of patients with vertigo and 18.7% with dizziness (p = 0.003). SVV SE incidence was higher in UH (64.7%) Conclusions: A slight SVV tilt persists between vertigo attacks and correlates with migraine imbalance underlying side-prevalent symptoms.
