BACKGROUND AND OBJECTIVE Although the relationship between day-to-day temperature changes and COPD mortality is well established, it is not known whether temperature variation within one day, that is diurnal temperature range (DTR), is a risk factor for acute COPD death, independent of the absolute temperature level. METHODS In a time-series study, the relationship between DTR and daily COPD mortality between 2001 and 2004 in Shanghai, China was assessed. A semi-parametric generalized… CONTINUE READING
