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

objectiveThe aim of this study is to explore the effect of stimulus frequency on air-conducted cervical and ocular vestibular evoked myogenic potential (cVEMP and oVEMP) in healthy subjects.

methodsThe study included 45 healthy subjects who underwent the VEMP tests. Different stimulus frequencies (250-1500 Hz) were used for air-conducted cVEMP and oVEMP.

resultsIn cVEMP, P1 and N1 latencies were significantly affected by different frequencies (P < .01). The amplitude at 500 Hz was significantly larger than those at other frequencies (P < .01).There was no significant main effect of frequency on asymmetry ratio (AR) (P > .05). In oVEMP, there was a tendency for the N1 and P1 latencies to decrease from 250 Hz to 1500 Hz (P < .01). The amplitudes at 500 Hz and 1000 Hz were significantly larger than the amplitudes at 250 Hz and 1500 Hz (P < .01).There was no significant main effect of frequency on AR (P > .05).

conclusionThe optimal stimulus frequency of the cVEMP is 500 Hz and for the oVEMP is 500Hz or 1000Hz. Due to the absence of impact of stimulus frequency, AR is the best parameter of VEMP for clinical use.
