Multiparameter Calibration of a Natural History Model of Cervical Cancer (2007)

Kim, Jane J., Kuntz, Karen M., Stout, Natasha K., Mahmud, Salaheddin, Villa, Luisa L., Franco, Eduardo L., ...

The objective of this study was to develop a comprehensive natural history model of human papillomavirus (HPV) and cervical cancer using a two-step approach to model calibration. In the first step,...

Expression of a novel non-coding mitochondrial RNA in human proliferating cells (2007)
