Chao1 diversity index of bacterial composition in fecal samples. Chao1 index values for stool samples of healthy volunteers (black circles) and ICU patients (colored circles) are ordered as follows (left to right): 1 to 5, healthy volunteers; 6 and 7, ICU1-1 and ICU1-2; 8 to 11, ICU2-1 to ICU2-4; 12 to 15, ICU3-1 to ICU3-4; 16 to 19, ICU4-1 to ICU4-4; 20, ICU5-1; 21 and 22, ICU6-1 and ICU6-2; 23, ICU8-1; 24, ICU9-1; 25, ICU10-1; 26 to 30, ICU11-1 to ICU11-5; 31, ICU12-1; 32, ICU13-1; 33, ICU14-1; and 34 and 35, ICU15-1 and ICU15-2. The horizontal dashed lines corresponding to Chao1 index values <50 and <10 represent arbitrary cutoffs. For the samples in this study, 14 had Chao1 index values of <10, 12 had Chao1 index values of 10 to 15, and 9 had Chao1 index values of >50. Mean Chao1 index value, 33; median, 25; range, 1.46 to 100.24.
