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

purposeSeveral studies have demonstrated the validity, reliability, and safety of drug-induced sedation endoscopy (DISE) in assessing the collapse of the upper airway (UA) in patients with obstructive sleep apnea hypoapnea syndrome (OSAHS). The aim of this study was to assess the interobserver agreement on DISE and on therapeutic decision between an expert observer and an observer in training.

methodsThis was a cross-sectional study. Thirty-one DISE videos performed in our service were randomly selected. Videos belonged to patients with OSAHS who wanted alternative treatments to CPAP. The videos were reviewed by an ENT experienced on DISE and a second observer in formation. Each observer independently assessed the presence of collapse of the UA according to a modified VOTE classification and proposed an alternative treatment to CPAP. Interobserver agreement kappa values were calculated.

resultsIn assessing the presence of collapse at different levels of the upper airway, the percentage of agreement was 80 % at the level of the soft palate (kappa = 0.1667), 89.29 % in the oropharynx (k = 0.7742), 80.65 % at the tongue base (k = 0.5571), and 74.17 % at the epiglottis (k = 0.4768). When degree and configuration of the collapse was evaluated, the interrater agreement was moderate to good, except at the level of the tongue base where the agreement was weak for both degree and configuration of collapse (k = 0.34 and 0.38, respectively). Interobserver agreement was moderate when the indication of alternative treatments to CPAP is valued based on the findings of DISE.

conclusionsOverall, DISE is a reliable technique even when assessing interobserver agreement between an experienced observer and one in training; however, tongue base is the level of the upper airway that presents the greatest difficulties when assessing the collapse with DISE. Therefore, it is important to develop learning curves for this technique in order to obtain more reliable results.
