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

backgroundThe laryngeal adductor reflex (LAR), a reflexive vocal fold closing mechanism, includes an early, probably di- or oligosynaptic ipsilateral LAR1- and a late ipsilateral and contralateral LAR2 polysynaptic component. In a clinical evaluation of dysphagia the LAR can be triggered by air pulses or tactile stimuli and typically assessed only qualitatively. METHODOLOGY: The development and construction of a device that can selectively shoot very small water droplets (microdroplet impulse testing MIT).

resultsThe MIT device has a water reservoir with an infinitely adjustable pressure. The opening period of the piezo-electrically operated valve determines the droplet size. With a high-speed camera system, the change in the airspeed of the drop can be determined, depending on the set water reservoir pressure. With the knowledge of the droplet size, the shooting speed and the estimation of the distance between the valve and laryngeal mucosa or airspeed can be determined the muzzle energy. By mounting the MIT device to a high speed glottography system, the time between the impact of the droplet on the laryngeal mucosa and the start of the laryngeal adduction, the LAR latency can be determined using an image by image evaluation. DISCUSSION: In dysphagia with penetration or aspiration it is presumed that the protective function of the larynx is no longer adequately ensured. The MIT-LAR device provides a valid and reliable method to assess LAR quantitatively. Furthermore, it holds the promise of being a simple to handle method that can be used clinically for routine diagnostics.
