The authors have advised due to an error at the time of figure assembly, Figure 4 on page 218 is incorrect. The correct Figure 4 is shown below.

Figure 4 The effect of mean temperature (°C) and apparent temperature on AECOPD hospitalizations along days of lag. The black lines are relative risks and grey regions are 95% confidence intervals.

Notes: The definitions of extreme cold, moderate cold, moderate hot, and extreme hot temperatures are the same as those in the footnotes of Tables 3 and 4.

The authors apologize for this error and advise it does not affect the results of the paper.
