Mean micronucleus (MN) yields and G2/M checkpoint efficiency ratios obtained with the G2 MN assay in healthy volunteers and BRCA1 mutation carriers. Significance was determined with a two-sided t test. p Values for each of the endpoints and dose points are indicated in the graph. Error bars represent the standard error of the mean.
