Pre and post-intervention LDA and correlation analyses. (a) LDA for the lemon-chilli pickle intervention group participants at three points. (b) LDA for the Onion pickle intervention group participants at three time points. (c) Cladogram of distinct taxa in the lemon-chilli pickle intervention group participants. (d) Cladogram of distinct taxa in the onion pickle intervention group participants. (e) Correlation analysis of pre (week-0) and post (week-8) distinct taxa with clinical biomarkers in the lemon-chilli pickle intervention group. (f) Correlation analysis of pre (week-0) and post (week-8) distinct taxa with clinical biomarkers in the onion pickle intervention group participants. The taxa belonging to the same group with the same relative abundance were considered one. In a heatmap, yellow squares indicate significant positive correlations (rho > 0.5, p < 0.05, Spearman correlation) and blue squares indicate significant negative correlations (rho < − 0.5, p < 0.05, Spearman correlation). (The letter before the taxa represents taxonomic rank: “p_” for phylum; “c_” for class; “o_” for order; “f_” for family; “g_” for genus; and “s_” for species. And “sp.” indicates an unidentified species name using the database.).
