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

objectiveCreak is an acoustic feature that serves an umbrella term for irregularities in fundamental frequency. This study evaluated whether automated creak distinguished speakers with adductor laryngeal dystonia (AdLD), primary muscle tension dysphonia (pMTD), and those without voice disorders during conversational speech.

methodsTwo stimulus types (reading passage and conversational speech) were produced by 50 speakers with AdLD, 50 speakers with pMTD, and 50 control speakers. An automated creak detector was used to calculate the percentage (%) of creak in both stimuli. The effects of group, stimulus type, and their interaction on % creak were assessed. Receiver operating characteristic curve analyses were conducted and the area under the curve (AUC) was used to evaluate the effectiveness of the creak detector in distinguishing among groups.

resultsWe found a statistically significant effect of group on % creak, but no effect of stimulus type on % creak, suggesting that creak distinguished speakers with AdLD, pMTD, and controls during both a reading passage and conversational speech. AUC values indicated acceptable discriminative ability in distinguishing AdLD speakers from both pMTD speakers and controls across both stimuli types.

conclusionAutomated creak demonstrates promise as a discriminative feature for identifying differences between speakers with AdLD from pMTD and controls in both a reading passage and conversational speech. LEVEL OF EVIDENCE: 3:
