“Application of Pharmacokinetically Guided Dose Escalation With Respect to Cell Cycle Phase Specificity,” by E. Fuse, S. Kobayashi, M. Inaba, et al. [J Natl Cancer Inst 86:989-996, 1994 (Issue 13)]. Because of a printer's error, information was omitted from three of the figures: logSS/N =0.149 [Fig. 1]; logSS/N = 1.629 [Fig. 2]; logSS/N [above the numbers 0.190 and 0.078 in Fig. 3]. The Journal regrets the error.
