Obstructive Sleep Apnea Increases the Risk of Cardiopulmonary Adverse Events Associated with Ambulatory Colonoscopy Independent of Body Mass Index.
Article in Digestive diseases and sciences, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
backgroundThe relationship between body mass index (BMI) and cardiopulmonary adverse events (CAEs) for ambulatory colonoscopy is unclear.
aimTo assess the association of BMI and CAEs associated with ambulatory colonoscopy.
methodsThis is a retrospective cohort analysis of 418 patients who underwent outpatient colonoscopy at the Durham Veterans Affairs Medical Center categorized as normal/overweight (BMI < 30), obese (BMI 30-34), or morbidly obese (BMI ≥ 35). Adjusted logistic regression analyses were performed.
resultsAt least one CAE occurred in 46.4% of patients (220 events, 72.7% were hypoxia). The rate of CAEs (BMI < 30: 43.8%, BMI 30-34: 48.0%, BMI ≥ 35: 50.6%, p = 0.53) and rate of hypoxia (BMI < 30: 34.8%, BMI 30-34: 40.9%, BMI ≥ 35: 43.2%, p = 0.32) were numerically higher for obese and morbidly obese patients, but not statistically significant. Obese (OR 1.10, 95% CI 0.70-1.73) and morbidly obese (OR 1.07, 95% CI 0.61-1.85) patients did not have an increased risk of CAEs after adjusting for age, ASA class, obstructive sleep apnea (OSA), and type of sedation. OSA was independently associated with an increased risk of CAEs (OR 1.71, 95% CI 1.09-2.74, p = 0.02) after adjusting for BMI, age, ASA class, and type of sedation.
conclusionOSA confers a higher risk of CAEs independent of BMI and sedation type. Consideration of undiagnosed OSA is recommended for appropriate pre-procedure risk stratification. While not statistically significant in this study, there may be clinically significant increased risks of CAEs and hypoxia for patient with BMI > 30 that require further evaluation with larger studies.
