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
objectiveTo evaluate video head impulse testing (vHIT) outcomes in patients with benign paroxysmal positional vertigo (BPPV) before canalith repositioning maneuver (CRM), immediately after treatment, and 1 week post-treatment. STUDY
designProspective before-after study.
settingTertiary referral center. PATIENTS: Of 156 patients with vertigo and positional nystagmus, 63 were diagnosed with BPPV using standard maneuvers; 51 had posterior canal BPPV, 11 had lateral canal BPPV and 1 had anterior canal BPPV. All underwent vHIT to assess vestibulo-ocular reflex (VOR) gain across all 6 semicircular canals and completed the Dizziness Handicap Inventory before and after treatment.
interventionsCRMs specific to the affected canal.
main outcome measuresVOR gain and Dizziness Handicap Inventory scores before and after CRM.
resultsAt pre-treatment, 59 patients (93.7%) exhibited VOR gains within normative limits. Only four patients (6.3%) showed decreased VOR gains, all of whom were diagnosed with posterior canal BPPV. VOR gain did not differ significantly across pre-treatment, immediate post-treatment, and 1-week assessments. No corrective saccades were detected.
conclusionsvHIT showed no significant post-treatment changes and may have limited incremental value in the routine evaluation of isolated BPPV cases.
