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.

Abstract

STUDY

objectivesA recent trend in increasing rates of severe maternal morbidity and mortality despite quality improvements has been noted. The goal of this study is to estimate the national prevalence of obstructive sleep apnea (OSA) in pregnant women and examine associations between OSA and pregnancy-related morbidities, including in-hospital maternal mortality.

designA retrospective, cross-sectional analysis.

settingA nationally representative sample of maternal hospital discharges from 1998-2009. PATIENTS OR

participantsThe analytic sample included 55,781,965 pregnancy-related inpatient hospital discharges.

interventionsN/A. MEASUREMENTS AND

resultsThe Nationwide Inpatient Sample (NIS) database was used to identify hospital stays for women who were pregnant or gave birth. Among these women, we determined length of hospital stay, in-hospital mortality, and used International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes to identify OSA and other outcome measures. Multivariable logistic regression modeling was used to calculate adjusted odds ratios (OR) and 95% confidence intervals (CI) for the associations between OSA and each outcome. The overall rate of OSA was 3.0 per 10,000; however, the rate climbed substantially from 0.7 in 1998 to 7.3 in 2009, with an average annual increase of 24%. After controlling for obesity and other potential confounders, OSA was associated with increased odds of pregnancy-related morbidities including preeclampsia (OR, 2.5; 95% CI, 2.2-2.9), eclampsia (OR, 5.4; 95% CI, 3.3-8.9), cardiomyopathy (OR, 9.0; 95% CI, 7.5-10.9), and pulmonary embolism (OR, 4.5; 95% CI, 2.3-8.9). Women with OSA experienced a more than fivefold increased odds of in-hospital mortality (95% CI, 2.4-11.5). The adverse effects of OSA on selected outcomes were exacerbated by obesity.

conclusionsObstructive sleep apnea is associated with severe maternal morbidity, cardiovascular morbidity, and in-hospital death. Targeted interventions may improve pregnancy outcomes in this group.
