Correlation analysis of the gut archaeal taxa and host factors. Spearman’s rank correlation coefficients and the corresponding P values were calculated based on comparisons of the relative abundance of abundant archaeal taxa at the genus level and the host factors, including dietary nutrients and clinical phenotypes. For orphan sequences (i.e. unclassified at the genus level), a high-rank lineage is provided. BMI body mass index, Hb haemoglobin, TotalC total cholesterol, LDLC low-density lipoprotein cholesterol, HDLC high-density lipoprotein cholesterol, TG triglyceride, γGT gamma-glutamyltransferase, AST aspartate transaminase, ALT alanine transaminase, SBP systolic blood pressure, DBP diastolic blood pressure, eGFR_MDRD estimated glomerular filtration rate using the MDRD formula, eGFR_CKDEPI estimated glomerular filtration rate using the CKD-EPI formula. Correction for multiple comparisons used the false discovery rate (FDR; threshold of 0.05). *Adjusted P < 0.05
