The authors regret that there were three data number errors in the Table 3 of the published paper, please kindly check below details:
The 95% upper confidence interval for 3-month average PM10 in basic model (single size fraction model) should be 0.01 instead of −0.001;
The 95% upper confidence interval for 12-month average PM10 in basic model (single size fraction model) should be 0.009 instead of−0.001;
The 95% upper confidence interval for 3-month average PM2.5 in multivariable-adjusted model (two size fraction model) should be 0.003 instead of −0.001.
These data number errors occurred during the process of rounding. The authors would like to apologise for any inconvenience caused.
