Correlation of bacterial richness using OTUs (A), bacterial evenness using SDI (B),
Bacteroidetes relative abundance (C), and Firmicutes relative abundance (D) with
ornithine flux in all 12 study participants [6 recent-onset KPD patients and 6 age-,
gender-, and BMI-matched control participants]. KPD, ketosis-prone diabetes; LBM,
lean body mass; OTU, organizational taxonomic unit; SDI, Shannon diversity
index.
