Literature was extracted from the Web of Science Core Collection database and was downloaded on October 24, 2022. The search strategies was as follows: TS= (NASH) OR TS= (non-alcoholic steatohepatitis) OR TS= (nonalcoholic steatohepatitis) OR TS= (NAFLD) OR TS= (non-alcoholic fatty liver disease) OR TS=(nonalcoholic fatty liver disease)OR TS=(MAFLD) OR TS=(metabolic associated fatty liver disease))AND ((TS= Liver (Topic) or TS= (hepatic*)) AND (TS= (gastro* micro*) or TS= (gastro* flora*) or TS=(gut micro*) or TS=(gut flora) or TS=(intestin * micro*) or TS=(intestin * flora))) OR (TS=(gut−liver axis) or TS=(gut liver axis)).We totally retrieved 2037 records. Then we eliminated invalid documents, including meeting abstracts (88), editorial materials (38), corrections (6), and letters (14). By this filter, 1891 records were included, of which articles (1209) accounted for 63.93% of the total, followed by reviews (682, 36.06%). This data extraction and exclusion were independently by two authors (SJY and DSY) and any disagreement was resolved by consulting the corresponding author (JJL). All data was exported and stored in the Data folder in the download_txt format at last.
