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

The Iowa Test of Consonant Perception (ITCP) was designed to test word-initial phoneme perception by uniformly sampling frequently used phonemes as well as balancing feature overlap of response competitors. However, the task has only been validated in normal hearing listeners. In this study, a large cohort of cochlear implant users completed the ITCP and two commonly used clinical measures of speech recognition [AzBio sentences and consonant-nucleus-consonant (CNC) words]. At two different signal-to-noise ratios, the ITCP showed strong convergent validity with other speech recognition tasks and good test-retest reliability. The ITCP is a useful tool for both clinicians and experimental researchers.
