a: The annotation for each compound is based on the HMDB database. b: The identification level of metabolites refers to the Metabolomics Standards Initiative reported by Sumner and coworkers. c: Accurate mass and RT were obtained from the mass spectrometer (Q Exactive) on full-scan mode. d: Calculated by Student’s t-test. Test level a = 0.05 and p < 0.05 means that the distribution of this metabolite between the fatal-intoxication group (at a high dose) and controls was significant. e: Comparison with controls. f: The VIP value is used to measure the ability of each metabolite to explain fatal intoxication, thereby assisting in the screening of marker metabolites (usually with VIP > 1.0 as the screening criterion).
