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

backgroundWith the current obesity epidemic, obstructive sleep apnea (OSA) has become increasingly common. Several studies have reported on the risk of post-operative complications in OSA patients undergoing non-upper airway surgeries. The objective of our study was to systematically review the medical literature reporting the incidence of post-operative complications in patients with OSA.

methodsWe conducted a systematic review using the Cochrane Collaboration Methodology. We searched Medline via Ovid, Pubmed, Embase, and Evidence-Based Medicine Reviews databases from 1950 to 2012. We rated the quality of evidence for each outcome using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. Meta-analysis was done using Review Manager Version 5.0.20.

resultsOur search resulted in 18 eligible studies. OSA was found to be associated with a significantly increased incidence of post-operative hypoxemia (odds ratio [OR] = 3.06; 95% confidence interval [CI] 2.35-3.97), respiratory complications (OR = 2.77, 95% CI 1.73-4.43), cardiac complications (OR = 1.76 95% CI 1.16-2.67), neurological complications (OR = 2.65, 95% CI 1.43-4.92), and unplanned intensive care unit (ICU) transfer (OR = 2.97, 95% CI 1.90-4.64). Re-intubation (OR = 1.37, 95% CI 0.65-2.91) was not significantly increased in patients with OSA. The association between OSA and post-operative outcomes remained unchanged with sub-group analysis including only studies that used polysomnography (PSG) for diagnosis.

conclusionsOSA patients are at increased risk of post-operative complications from non-upper airway surgeries. Early diagnosis and treatment of OSA might decrease post-operative complications in these patients. There is a need for further studies to assess the benefit of peri-operative treatment of OSA on post-operative outcomes.
