JAMA. 2002;288:1985.

In the Original Contribution entitled "Association of Sleep-Disordered Breathing, Sleep Apnea, and Hypertension in a Large Community-Based Study," published in the April 12, 2000, issue of THE JOURNAL (2000;283:1829-1836), there was incorrect wording in the abstract and in the "Methods" section. On page 1829 in the "Main Outcome Measures" section the sentence that read "(AHI, the average number of apneas plus hypopneas per hour of sleep, with hypopnea defined as a 30% reduction in airflow or thoracoabdominal excursion accompanied by a 4% drop in oxyhemoglobin saturation)," should have read "(AHI, the average number of apneas plus hypopneas per hour of sleep, with apnea defined as a cessation of airflow and hypopnea defined as a 30% reduction in airflow or thoracoabdominal excursion, both of which are accompanied by a 4% drop in oxyhemoglobin saturation)."

On page 1830, in the "Study Variables" section, the sentence that read, "Sleep-disordered breathing was assessed using the apnea-hypopnea index (AHI), defined as the average number of apneic plus hypopneic episodes per hour of sleep. Apnea was defined as a complete or an almost complete cessation of airflow and hypopnea as a decrease in airflow or thoracoabdominal excursion of at least 30% of baseline for 10 seconds or more, accompanied by a 4% or more decrease in oxygen saturation" should have read, "Sleep-disordered breathing was assessed using the apnea-hypopnea index (AHI), defined as the average number of apneic plus hypopneic episodes per hour of sleep. Apnea was defined as a complete or an almost complete cessation of airflow and hypopnea as a decrease in airflow or thoracoabdominal excursion of at least 30% of baseline for 10 seconds or more. Both apnea and hypopnea must be accompanied by a 4% or more decrease in oxygen saturation."

On page 1831 in the Alcohol intake section of Table 1, the number of drinks consumed should be by the week and not by the day.
