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

purposeThe purpose is to investigate possible vestibulopathy in patients with benign paroxysmal positional vertigo (BPPV), inner ear tests, including cervical and ocular vestibular-evoked myogenic potentials (cVEMPs and oVEMPs) via various stimulation modes, were adopted.

methodsFifty BPPV patients were enrolled in this study. All patients underwent pure tone audiometry, cVEMPs, oVEMPs, and caloric tests. The recurrence status, abnormal rates of inner ear tests, and the characteristic parameters of VEMPs, such as wave latencies and amplitudes, were analyzed.

resultsIn affected ears, the abnormal rates of acoustic cVEMPs, vibratory oVEMPs, galvanic cVEMPs, and galvanic oVEMPs were 62%, 28%, 36%, and 14%, respectively. The abnormalities of acoustic cVEMPs were significantly larger than those of vibratory oVEMPs, and acoustic/vibratory VEMPs had significantly higher abnormal rates than the corresponding galvanic VEMPs.

conclusionBPPV patients may have both otolithic and neural dysfunctions. Otolithic organ damage occurs more frequently than retrootolithic neural degeneration, and the saccular macula might have a greater extent of damage than the utricular macula.
