1 · What the graph read from it

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.

2 · The registry

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

Auditory stream segregation was measured using ABA-ABA sequences where A and B were the vowel |α| and A and B differed in fundamental frequency by ΔF0. The aim was to assess the impact of ΔF0 and inter-stimulus interval (ISI) on stream segregation for normal-hearing (NH) and hearing-impaired (HI) participants with mild-to-moderate hearing loss. For each ISI, ΔF0 was varied using an adaptive procedure to estimate the temporal coherence boundary (TCB, the ΔF0 for which two streams were mostly reported) and the fission boundary (FB, the ΔF0 for which one stream was mostly reported). The TCB and FB were smallest for an ISI near 50 ms. The increase for smaller ISIs may reflect a tendency for the sequences to be perceived as a single frequency-modulated sound, while the increase for larger ISIs may reflect the effectiveness of F0 differences in promoting stream segregation when a sequence of discrete sounds is perceived. The TCBs were higher for the HI than for the NH participants for all ISIs, while the FBs were higher for the HI participants mainly for ISIs above 50 ms. The higher TCB and FB values for the HI participants probably reflect the reduced salience of fundamental frequency differences.
