Each of 5,000 vectors of 2,376 conditional individual median doses were obtained from 100× resampling of unshared parameters in the inner loop of the 2DMC dose reconstruction model to produce 100 random individual dose estimates per subject, each “conditioned” on a unique fixed set of outer loop parameter values that are shared by cohort subgroups. The set of shared outer loop parameter values was resampled 1× for each successive dose vector and the 100× inner loop resampling was repeated, until 5,000 vectors of conditional individual median doses were produced.
