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
purposeMasseter vestibular-evoked myogenic potentials (mVEMPs) assess vestibular function through the vestibulo-masseteric reflex. While tone burst (TB) stimuli are commonly used, narrowband chirp stimuli may improve response rates and neural synchronization. This study compares the effectiveness of TB and chirp stimuli in bone-conducted mVEMP testing.
methodsThirty-five healthy participants (70 ears) underwent mVEMP testing using a bone conduction vibrator. We evaluated response obtainability, P1 and N1 latencies, and P1-N1 amplitude in bone-conducted mVEMPs using 500 Hz TB and 500 Hz narrowband level-specific (NB LS) chirp stimuli.
resultsThe response rate for the NB LS chirp stimulus (80.0%) was significantly higher than that for the TB stimulus (42.9%) (p < 0.001). Logistic regression analysis indicated that the likelihood of obtaining a response with chirp stimuli was 5.333 times higher than with TB stimuli (p < 0.001). Additionally, chirp stimuli produced significantly shorter latencies and higher amplitudes (p < 0.001).
conclusionIn bone-conducted mVEMPs, NB LS chirp stimuli improve response rates, shorten latencies, and increase amplitudes, suggesting greater reliability and efficiency in vestibular assessment.
