The Time of the Insult/Triggering Event in Primary Osteosarcoma and Ewing’s Sarcoma of Bone as Determined by Incubation Period Modeling and Age Distribution of Such Malignancies

Figure 1

Asymmetric single peak distribution function fits for long bone conventional osteosarcoma with the Pearson IV (a) and log normal distribution (b). The log normal distribution is a slightly better fit at the young ages but does not capture the peak age of 15 years as well as the Pearson IV distribution.
