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

objectiveThis study aimed to determine (1) how cepstral peak prominence (CPP) and the amplitude difference between the first two spectral harmonics (H

methodAcoustic voice recordings were obtained from 50 vocally healthy individuals. Speech tasks included five repetitions of three sustained vowels (/ɑ, i, u/) and one all-voiced sentence ("We were away a year ago") using three voice production conditions (typical, breathy, and pressed). For each production, we calculated average smoothed CPP and H

resultsIn connected speech, pressed phonation demonstrated higher CPP and lower H

conclusionCPP and H
