a

Mean for 10 subjects.

b

Mean for 60 subjects.

c

Values converted from mean mutagenic potencies in rev/µmole creatinine (Fig. 2A and 2B) assuming 13964 µmole creatinine per 12 h urine sample. This conversion factor was a median based on 36 samples (4 samples each for 8 subjects; 1 sample each for 4 subjects) of first morning voids. Although we measured creatinine concentrations for all 64 samples (4 samples each from 16 subjects), we failed to record urine volume for 28 (4 samples each for 4 subjects plus 3 samples each for 4 subjects).

d

Values converted from mean mutagenic potencies in rev/mg lyophilized feces (Fig. 2C and 2D) assuming 19.32 g lyophilized feces per movement. This conversion factor was a median based on 32 fecal samples (2 samples each for 16 subjects).
