1 · What the graph read from it

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.

2 · The registry

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

Background: The canalith repositioning maneuver (CRM) is an effective method for treating benign paroxysmal positional vertigo (BPPV). Classical CRM is designed mainly for a single semicircular canal (SC). Methods: A mixed maneuver (MM) hybridized by classical maneuvers was proposed for otoconia of three SCs on the same side. Simulations of otoconia movement induced by classical CRMs and MM were performed on a 3-axis servo motors platform (SMP) with an iPhone containing the aVOR app. MM was performed on BPPV VIEWER to show the otoconia trajectory. Results: The Epley and Barbecue maneuver were effective for the otoconia of posterior semicircular canal (PSC) and horizontal semicircular canal (HSC), respectively. Similarly, the supine roll test + Gufoni maneuver was effective for otoconia of HSC, and the Dix-Hallpike test + Yacovino maneuver was effective for otoconia of ASC. Furthermore, the MM was effective for free-floating otoconia in HSC, ASC and long arm of PSC on the same side. Conclusion: The SMP-aVOR model and BPPV VIEWER provide methods for studying otoconia repositioning. The MM showed potential capability to reposition the common types of otoconia in the three SCs on the same side.
