BMD based on a Log-logistic dose–response model for micronucleus damage.

Group N b0 b1 BMD10 (mg/m3) BMDL10 (mg/m3)
Total 483 −2.66 1.00 1.68 1.09
Male 369 −2.13 1.00 1.23 0.54
Female 114 −1.45 1.82 0.67 0.23

Model: P [MN damage] = c + (1 − c)/[1 + EXP (−a − b * log (dose))]. Excess risk at BMD is 10% above reference risk in the remaining normal population. Goodness-of-fit test (P-value) indicated the model fitted the data well. BMD: benchmark dose; BMDL: lower confidence bound on the BMD. Total: all individuals in this study.
