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

rationaleRetrospective studies indicate that obstructive sleep apnea occurs often after aneurysmal subarachnoid hemorrhage. We aim to investigate if obstructive sleep apnea is associated with impaired blood pressure control early after subarachnoid hemorrhage.

methodsPatients with subarachnoid hemorrhage were recruited and screened for sleep apnea using cardiorespiratory polygraphy within 48 h after intensive care unit admission, and 6 months after hospital discharge at home. Blood pressure was continuously measured using intra-arterial catheter within the first 24 h after admission. Time between hospital admission and first blood pressure below 140 mmHg, and time with elevated blood pressure within the first 24 h after admission were compared between patients with and without obstructive sleep apnea.

resultsOf 60 patients, 55 successfully completed the study. Obstructive sleep apnea (AHI > 5/h) was diagnosed in 32% of men and 24% of women. While the time to reach a blood pressure of 140 mmHg did not differ (60.0 ± 26.2 min vs. 49.7 ± 16.4 min; p = 0.74), obstructive sleep apnea patients spent more time with blood pressure above 140 mmHg (292.0 ± 114.0 vs. 96.9 ± 28.3 min per 24 h; p = 0.025, CI 95 -363.6 to -26.5) within the observational period. Only AHI and diagnosed hypertension were significant predictors for elevated blood pressure (R

conclusionObstructive sleep apnea is associated in our study with poor blood pressure control early after subarachnoid hemorrhage. These patients may need advanced management for blood pressure including management for OSA following subarachnoid hemorrhage. Screening for sleep apnea in patients with subarachnoid hemorrhage is recommended.
