Positional Convergence Spasm: A Case Report.
Article in Cureus, 2025. 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
Benign paroxysmal positional vertigo is one of the most common causes of vertigo. Although quite bothersome, this condition can be easily treated using simple maneuvers. Sudden-onset diplopia, on the other hand, may indicate serious medical conditions. On rare occasions, diplopia may be related to psychogenic convergence spasm and can be induced by positional maneuvers. We report the case of a patient presenting positional vertigo and brief episodes of diplopia without nystagmus, in whom psychogenic convergence spasm was provoked during positional testing. This rare phenomenon highlights the importance of considering functional etiologies in the differential diagnosis of atypical vertigo presentations to avoid unnecessary investigations.
