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
BACKGROUND AND
objectivesThis study aimed to establish normative data and evaluate the test-retest variability of 4 kHz pure-tone psychoacoustic tuning curves (PTCs) measured using a conventional two-channel clinical audiometer. Materials and.
methodsThirty-four adults with normal hearing (≤25 dB HL) underwent two PTC testing sessions separated by a 2-week interval. A 4,000-Hz signal tone presented at 10 dB above threshold and seven pure-tone maskers (3,150-4,896 Hz) were administered using an Interacoustics AC40 Audiometer through the 3-down/1-up approach. Participants were randomly assigned to either low-to-high or high-to-low masker-frequency-order groups. Test-retest variability was analyzed across masker frequencies, and correlations with participant demographics were determined. Q10 values were evaluated as indices of frequency selectivity.
resultsAll participants completed the testing without auditory discomfort. Approximately 80% had a test-retest variability of ≤8 dB, indicating high reliability. The largest intersession differences were observed at 4,896 Hz (9.80±7.35 dB) and 3,150 Hz (5.77±6.95 dB). Test-retest variability was positively correlated with age (r= 0.50, p=0.006). The mean Q10 was 5.76±1.72, and decreased significantly with age (r=-0.49, p=0.014). The average tuning curve exhibited a V-shaped pattern with a tip at 4,000 Hz, consistent with classical findings.
conclusionsThe simplified pure-tone PTC protocol using a standard clinical audiometer provided reproducible and relevant estimates of auditory frequency selectivity. These findings support its clinical feasibility for assessing frequency selectivity and age-related changes in the auditory filter.
