a: The annotation for each compound was based on the HMDB database; b: accurate mass and retention time were obtained from the Q Exactive mass spectrometer on a full-scan model; c: the mass spectrometry data were analyzed by CD 3.1 software (version, Manufacturer name, city, state abbreviation if US or Canada, country) to obtain; d: calculated with student’s t-test. p < 0.05 means that differences in this metabolite between EFI and the controls are significant; e: Combined Log FC: in the biomarker meta-analysis, the mean of fold-change for the metabolite in the experimental group relative to the different control groups is one of the main bases for screening the common differential metabolites; f: trend compared to the control group; g: combined VIP: this value represents the ability of each metabolite to explain estazolam fatal intoxication, and is the mean value of the VIP-value of the experimental group and each control group and auxiliary screening for differential metabolites (the usual screening criterium is VIP > 1).
