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 study investigated the swallowing dynamics of jelly, thickened liquid, and thin liquid in selected stroke patients who exhibited near-normal swallowing function with screening tests. Videofluoroscopic examination compared the pharyngeal transit time (PTT), pharyngeal delay time (PDT), and laryngeal elevation delay time (LEDT). Of 175 patients (104 men, 71 women; mean age: 68.6 ± 12.0 years) evaluated, 24 (13.7%) experienced aspiration, significantly prolonging LEDT in swallowing thin liquid. PTT did not differ in swallowing jelly, thickened liquid, or thin liquid among the patients who did not aspirate. However, in two-phase analysis of PTT, performed before and after the jelly passed the epiglottis, the former was significantly prolonged, whereas the latter was significantly shortened. PDT was significantly longer with jelly than with thickened and thin liquids. LEDT was significantly longer in swallowing thin liquids. Apparently, the thin liquid reached the pyriform sinus before maximum laryngeal elevation, posing a risk of laryngeal penetration and aspiration during swallowing. A thicker liquid prolonged the time taken to reach the pyriform sinus, reducing aspiration risk. Moreover, oropharyngeal passage of jelly took longer, triggering the swallowing reflex around the vallecula and allowing the jelly to pass through the hypopharynx after laryngeal closure.
