Declarations

:

: All experimental protocols of this study were approved by the Ethics Committee of Anhui Medical University(No.83243452), and all methods were conducted according to the guidelines of the Declaration of Helsinki and relevant Chinese laws and regulations. We confirm that informed consent was obtained from all participants and/or their legal guardians. Considering that the study participants were all rural residents with generally low literacy levels, we used plain language to prepare the informed consent form, avoiding jargon and ensuring the clarity of the content. At the same time, before signing the informed consent form, the investigator explained the study purpose, procedures, potential risks and rights and benefits to the participants line by line, and for participants with limited comprehension, their family members or members of the village committee were invited to assist in the explanations to ensure that they fully understood the content of the study. Written informed consent was obtained from all participants before any study procedures were performed.
