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
Speech comprehension relies on temporal and spectral processing, which can be impaired by background noise. Traditional pure-tone audiometry in standard frequencies has limitations in predicting speech understanding under such conditions. Extended High Frequencies (EHFs) contribute to audibility and speech recognition. This study aims to investigate the correlation between EHF hearing, auditory temporal-spectral processing, and speech comprehension in background noise, and to analyze the factors influencing speech perception in noise ability in adults with normal hearing, emphasizing the importance of EHF evaluation in clinical settings. This cross-sectional study included 44 participants with normal auditory function. The participants underwent high-frequency audiometry, the Quick speech-in-noise (SIN) test for SIN comprehension evaluation, the Gap in Noise (GIN) test for temporal resolution assessment, and the Spectral-Temporally Modulated Ripple Test (SMRT) for spectral resolution examination. The study found a significant correlation between mean EHF thresholds and SNR loss in both common (
