Error in Text. In the Original Article titled 鈥淪leep in Lifetime Posttraumatic Stress Disorder: A Community-Based Polysomnographic Study,鈥� published in the May issue of the ARCHIVES (2004;61:508-516), an error occurred in the text. On page 512, in the subsection titled 鈥淪leep Breathing and Periodic Leg Movement,鈥� the first 2 sentences should have appeared as follows: 鈥淲e used a cutoff of 5 events/h to measure sleep breathing disturbances (apnea-hypopnea). Findings were 5.2% in the first night and 5.1% in the second night (P=.20).鈥� This correction does not change the observation of no significant difference between the first and second night.
