Objective To evaluate reporting condition of the published overview of systematic reviews of traditional Chinese medicine（TCM）.Methods The published Chinese medicine related Overviews were collected and identified by searching China Knowledge Network（CNKI）

China Biomedical Literature Database（CBM） and Wanfang Database from inception to 23 April 2018.The Preferred Reporting Items for Overview of systematic reviews（PRIO-harms） was used to assess the reporting condition.Results The searching identified 968 records and 21 were eligible for analysis finally.The included Overviews consisted of 5 to 69 systematic reviews

with a total of 362 systematic reviews.The PRIO-harms reporting quality assessment showed that the reporting of item 5 "protocol and registration"（0/21）

item 10 "additional search for primary studies"（0/21）

item 14 "Meta-bias（es） "（0/21）and item 18 "overlapping"（0/21） were totally neglected

while item 7 "information sources"（8/21） occupied the highest proportion 38% of all reports.The remaining items

especially for those involving harms

were mostly partreported.Conclusion The reporting specification of overviews of TCM was generally unclear

especially for those harm-related items

and the overall reporting specifications need to be improved.The PRIO-harms checklist should be applied as a guideline in reporting Overviews

so as to improve their integrity and transparency.
