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
To explore the applicability of discrete wavelet transforms in the analysis of vHIT responses. Discrete wavelet transform was applied to vHIT responses and a new method for calculating aVOR gain was developed. A prospective study was performed with two groups of normal (N = 10) and altered (N = 19) gain values; HIMP and SHIMP vHIT protocols were performed on both groups. To evaluate the gain values obtained, Intraclass Correlation Index, Pearson's correlation, linear regression, and t test were performed. Intraclass correlation indexes of 0.97 and 0.99 were determined for HIMP and SHIMP procedures performed on the proposed and standard gain calculation method. A significant difference of - 0.06 ± 0.07 (p < 0.001) was found between gain calculation methods for HIMP protocol. Significant differences were found (p < 0.001) between normal and altered groups for all gain calculation methods. Discrete wavelet transforms were successfully applied to measure head impulse test responses. Gain values obtained with this method appear to be valid and in concordance with gain values obtained with standard calculation method. However, a slight but significant difference was observed when this method was applied to tests obtained with HIMP.
