Spearman correlation analysis between gut microbiota and differential metabolites. (A) Correlation analysis in SLE-nonLN and SLE-LN groups. (B) Correlation analysis in HC and SLE-nonLN groups. The x-axis represents differential metabolites, while the y-axis denotes bacterial genera identified at the 16 S rRNA gene level. Red indicates a positive correlation, whereas blue represents a negative correlation. Asterisks indicate statistical significance: *p < 0.05, **p < 0.01
