Values are mean ± SE. The results estimated by the NCI MIXTRAN, DISTRIB, BRR_PVALUE_CI macros method were generated by using the example codes provided by the NCI website (available from: https://prevention.cancer.gov/research-groups/biometry/measurement-error-impact/software-measurement-error/single-regularly-consumed-or-1).
