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

purposeTo evaluate the effect of pharyngeal surgery on swallowing pattern in patients with obstructive sleep apnea syndrome (OSAS), and to compare two surgical techniques: uvulopalatopharyngoplasty (UPPP) and expansion pharyngoplasty (EP), through videofluoroscopy.

methodsLongitudinal prospective cohort, in a tertiary referral center. 17 adult patients were enrolled this study, divided into two groups: patients who underwent UPPP (n = 10) or EP (n = 7). Swallowing videofluoroscopy (for both liquid and pasty consistences) was assessed at three different periods: before surgery, and at 14 and 28 days following surgery. Comparisons were performed between pre- and post-operative (PO) swallowing conditions in the same patient, and between surgical techniques.

resultsAsymptomatic OSAS patients already presented altered swallowing pattern before surgery. Both surgical procedures led to an increased hyoid movement time and an increased frequency of laryngeal penetration in early PO during liquid ingestion. For pasty consistency, both techniques reduced velum movement time and increased pharyngeal transit time and the rate of stasis in hypopharynx. All these parameters reached or tended to reach the pre-operative indices at day PO 28.

conclusionsOSAS patients show sub-clinical changes in swallowing pattern before surgery. Both surgical techniques are related to transitory changes in swallowing biomechanics. Complete or partial reversal to pre-operative swallowing parameters occurs 1 month after both surgery techniques.
