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

This single-subject study used optical coherence tomography to image medial surface vibratory patterns during the production of chest, head, whistle, and creaky voice. Chest and head registers differed in medial surface thickness, with the chest voice produced with thicker vocal folds, greater vibratory amplitude, and a larger vertical phase difference than the head voice and the other voice qualities. The whistle voice was produced with tightly approximated vocal folds that were thicker than in the head voice and showed small but measurable vibrations. An alternating creaky and regular voice was produced without observable changes in vocal fold thickness.
