假设你是作者需要回复论文评审专家的意见请将下文的回复翻译问英文：抱歉我们在手稿中没有写清楚。在对稿件的分析中NDVI and PM25 were treated as continuous variables scaled to 01-unit increase and 10-μgm³ increase respectively。而不是用每改变一个四分位数。具体细节已在手稿中补充。

I apologize for the lack of clarity in our manuscript. In the analysis of the manuscript, NDVI and PM2.5 were treated as continuous variables scaled to a 0.1-unit increase and a 10-μg/m³ increase, respectively, rather than using a change in each quartile. Specific details have been added to the manuscript.
