These two papers describe the construction and empiric calibration of a cervical cancer microsimulation model at two time points, first leveraging primary data from a large epidemiological study (Kim et al.), and second leveraging data on type-specific HPV persistence and clearance from the control arm of vaccine trials (Campos et al.).
