Objective To re-evaluate the systematic review/Meta-analysis of acupuncture and moxibustion for childhood autism（CA）

aiming to provide decision-making basis for clinical diagnosis and treatment. Methods The systematic review and/or Meta-analysis of acupuncture and moxibustion for CA were searched in PubMed

EMbase

Cochrane Library

SinoMed

CNKI and Wanfang databases. The retrieval time was from the database establishment to May 5th

2022. PRISMA（preferred reporting items for systematic reviews and Meta-analyses） was used to evaluate the report quality

and AMSTAR 2（a measurement tool to assess systematic reviews 2） was used to evaluate the methodological quality

bubble map was used to construct the evidence map and GRADE was used to evaluate the quality of evidence.Results A total of 9 systematic reviews were included. The PRISMA scores ranged from 13 to 26. The report quality was low

and there was a serious lack in the aspects of program and registration

search

other analysis and funding. The main problems in methodology included not making prespecified protocol

incomplete retrieval strategy

not providing a list of excluded literatures

and incomplete explanation on heterogeneity analysis and bias risk. The evidence map showed that 6conclusions were valid

2 conclusions were possible valid and 1 conclusion was uncertain valid. The overall quality of evidence was low

and the main factors leading to the downgrade were limitations

followed by inconsistency

imprecision and publication bias. Conclusion Acupuncture and moxibustion has a certain effect for CA

but the quality of reporting

methodology and evidence in included literature need to be improved. It is suggested to perform high-quality and standardized research in the future to provide evidence-based basis.
