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 purpose of this article is to provide a theoretical account of the experience of stuttering that incorporates previous explanations and recent experimental findings. According to this account, stuttering-like disfluencies emerge during early childhood from excessive detection of cognitive conflict due to subtle limitations in speech and language processes. For a subset of children who begin to stutter, the development of approach-avoidance motivational conflict likely contributes to a chronic reliance on cognitive control processes during speech. Consequently, maladaptive activation of right hemisphere inhibitory cortices to the basal ganglia via a hyperdirect pathway results in involuntary, episodic, and transient freezing of the motor system during speech initiation. This freeze response, consistent with defensive behavior in threatening situations, may lead to stuttering persistence, tension and struggle, maladaptive speech physiology, and feelings of anxiety and loss of control.
