"RELATIONSHIP BETWEEN RESPIRATORY SYMPTOMS AND MEDICAL TREATMENT IN EXACERBATIONS OF COPD". P. CALVERLEY, R. PAUWELS, C-G. LÖFDAHL, K. SVENSSON, T. HIGENBOTTAM, L-G. CARLSSON AND E. STÅHL. EUR RESPIR J 2005; 26: 406–413.

Unfortunately, a small section of text in the above paper (in the Results, Individual changes: combined symptom scores, Symptom mean exceeding a set value) was reported incorrectly. It should have appeared as follows. "Symptom-based events, defined as a mean symptom value exceeding a level of 1.5, 2.0 or 2.5 for 3 consecutive days, showed a relatively high degree of concurrence at the lower levels (table 4). A symptom-based exacerbation, defined as a level of 1.5 for 3 days, was seen in almost all patients at some point, 63.3% correlating with an event-based exacerbation." The authors apologise for this error.
