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
backgroundThe vestibular evoked muscle potentials (VEMPs) test provides information about the otolith organs and the vestibular nerves. The usefulness of VEMP responses related to the trapezius muscle in the evaluation of the vestibular system remains uncertain. The present study sought to compare VEMPs recorded over the trapezius muscle (tVEMP) in extensor and flexor conditions with cervical VEMP (cVEMP) responses and to evaluate the applicability of tVEMP.
methodsA total of 22 healthy male subjects, aged between 19 and 38 years, were included in the study. After the hearing test, cVEMP and tVEMP were applied to all participants. Cervical vestibular evoked myogenic potential was applied over the sternocleidomastoid muscle (SCM), and tVEMP was applied over the trapezius muscle in both extensor and flexor conditions.
resultsThe absolute latency of the tVEMP flexor condition P1 was found to be significantly longer than that of the cVEMP P1 (P= .023). There was no significant difference in N1 latencies across all 3 test methods (P= .122). The amplitudes of tVEMP P1-N1 in the flexor condition were found to be significantly lower than those of both cVEMP and tVEMP in the extensor condition (P < .001).
conclusionA 500 Hz tone burst stimulus can elicit VEMP responses from the trapezius, and tVEMP can be used as an alternative to cVEMP. It seems that a significant benefit of the tVEMP extensor test is that it can be employed as an alternative in cases where cVEMP is not feasible.
