摘要：We thank Perry Gottesfeld and Yuyun Ismawati for their remarks. Our systematic review, 1 based on an assessment of probable sources of lead exposure in 1100 subsamples drawn from 478 studies published between 2010 and 2019, identified that lead- based paint did not seem to be a major source of lead exposure in low- income and middle-income countries (LMICs). Of the 1100 subsamples, only seven (1·5%) reported lead-based paint as a probable source of exposure. From this finding, we concluded that sources of exposure in LMICs appeared to be distinct from those in high- income countries (HICs), given that the primary sources of exposure in LMICs seemed to be industrial.
