Abstract

CONTEXT: Continuous positive airway pressure (CPAP) is the first-line treatment for patients with symptomatic obstructive sleep apnea (OSA). However, its indication for all patients with sleep-disordered breathing, regardless of daytime symptoms, is unclear. OBJECTIVE: To evaluate the effect of CPAP treatment on the incidence of hypertension or cardiovascular events in a cohort of nonsleepy patients with OSA. DESIGN, SETTING, AND PATIENTS: Multicenter, parallel-group, randomized controlled trial in 14 teaching hospitals in Spain. Between May 2004 and May 2006, 725 consecutive patients were enrolled who had an apnea-hypopnea index of 20 h(-1) or greater and an Epworth Sleepiness Scale score of 10 or less (scores range from 0-24, with values <10 suggesting no daytime sleepiness). Exclusion criteria were previous cardiovascular event, physical or psychological incapacity, chronic disease, or drug or alcohol addiction. Follow-up ended in May 2009. INTERVENTION: Patients were allocated to receive CPAP treatment or no active intervention. All participants received dietary counseling and sleep hygiene advice. MAIN OUTCOME MEASURES: Incidence of either systemic hypertension (taking antihypertensive medication or blood pressure greater than 140/90 mm Hg) or cardiovascular event (nonfatal myocardial infarction, nonfatal stroke, transient ischemic attack, hospitalization for unstable angina or arrhythmia, heart failure, or cardiovascular death). RESULTS: Seven hundred twenty-three patients underwent follow-up for a median of 4 (interquartile range, 2.7-4.4) years (1 patient from each group did not receive allocated treatment); 357 in the CPAP group and 366 in the control group were included in the analysis. In the CPAP group there were 68 patients with new hypertension and 28 cardiovascular events (17 unstable angina or arrhythmia, 3 nonfatal stroke, 3 heart failure, 2 nonfatal myocardial infarction, 2 transient ischemic attack, 1 cardiovascular death). In the control group there were 79 patients with new hypertension and 31 cardiovascular events (11 unstable angina or arrhythmia, 8 nonfatal myocardial infarction, 5 transient ischemic attack, 5 heart failure, 2 nonfatal stroke). The hypertension or cardiovascular event incidence density rate was 9.20 per 100 person-years (95% CI, 7.36-11.04) in the CPAP group and 11.02 per 100 person-years (95% CI, 8.96-13.08) in the control group. The incidence density ratio was 0.83 (95% CI, 0.63-1.1; P = .20). CONCLUSIONS: In patients with OSA without daytime sleepiness, the prescription of CPAP compared with usual care did not result in a statistically significant reduction in the incidence of hypertension or cardiovascular events. However, the study may have had limited power to detect a significant difference. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00127348.

  • Some RCTs that selectively recruited non-sleepy participants demonstrated no benefits in blood pressure or cardiovascular risk reduction with CPAP.

    “some RCTs that selectively recruited non-sleepy participants demonstrated no benefits in BP 63,86,106 or cardiovascular risk reduction 106,108 with CPAP.”

    From Treatment of Adult Obstructive Sleep Apnea With Positive Airway Pressure: An American Academy of Sleep Medicine Systematic Review, Meta-Analysis, and GRADE Assessment (2019) · cites this paper as [106]

    The COMMENT conclusion reports no statistically significant reduction in incident hypertension or cardiovascular events with CPAP in patients without daytime sleepiness, supporting the cardiovascular portion of the claim. The trial’s reported outcome was new-onset hypertension, not a demonstrated absence of benefit in blood-pressure levels; the authors also caution that limited power may have prevented detection of a difference.

  • Several other classifications, based on pathophysiology, comorbid conditions, and clinical outcomes, have also been described.

    “Several other classifications, based on pathophysiology,36 comorbid conditions,37 and clinical outcomes,38 have also been described.”

    From International Consensus Statement on Obstructive Sleep Apnea (2023) · cites this paper as [38]

    Citation 38 is attached to the claim about classifications based on clinical outcomes. The Outcomes and Follow-up section measures hypertension and cardiovascular events, while the Statistical Analysis section divides patients by disease severity and CPAP adherence; neither describes a classification based on clinical outcomes. I searched for outcome-based classification and risk stratification in our copy. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
