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

backgroundOf patients suspected as having obstructive sleep apnea (OSA) while undergoing routine gastrointestinal endoscopy under conscious sedation (GE-CS), 43% have severe disease but have never consulted specialist clinics because of the absence of significant symptoms/signs. If patients with possible severe OSA can be predicted during GE-CS, they could be advised to consult sleep specialist clinics. MATERIALS AND

methodsWe retrospectively analyzed data of 112 patients who were suspected as having OSA during GE-CS and underwent sleep apnea testing at our hospital, to evaluate whether patient characteristics, endoscopic detection of upper airway obstruction (UAO), and vital signs during routine GE-CS can predict the possibility of severe underlying OSA.

resultsThe mean age of the patients was 55 years, 74% were men, and 64% had obesity. Severe OSA was diagnosed in 13% of patients with mild UAO (< 50% luminal stenosis), 18% of patients with moderate UAO (50%-75% stenosis), and 45% of patients with severe UAO (> 75% stenosis). The UAO severity was positively correlated with the apnea hypopnea index score (r = 0.305, p = 0.001) and negatively correlated with the minimum SpO

conclusionNot only the presence of UAO, but also minimum SpO
