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

Cochlear-implant listeners show impaired pitch perception compared to normal-hearing listeners. One of the factors limiting pitch sensitivity in multi-electrode as compared to single-electrode stimulation can be intracochlear interactions of electrode signals (i.e., channels). We measured temporal-pitch discrimination sensitivity for loudness-balanced dual-electrode stimuli with various spatio-temporal configurations in listeners with MED-EL implants. We hypothesized a link between pitch sensitivity and tonotopic separation as well as (monaural) temporal electrode asynchrony, the latter resulting in various combinations of inter-pulse intervals in the compound stimuli received by the auditory nerve. Per-electrode stimulus types were high-rate (i.e., 1,000-pps) pulse trains with a 100-Hz amplitude modulation and both with and without additional pulses inserted with short inter-pulse intervals at modulation peaks. The temporal asynchrony had a detrimental effect for tonotopic separations below 2.2 mm but not for separations of 7.1 mm and more. This pattern was largely consistent across stimulus types and can be attributed to spectro-temporal channel interactions. When compared with sensitivity to unmodulated 100-pps pulse trains [Lindenbeck et al.,
