What was measured

The volume transfer constant (Ktrans) was used to evaluate clinical outcomes. The average for the distribution across the whole region of interest (ROI) was calculated as a summary measure for each data set.

Analysis population: The number analyzed at each time point differed due to missing observations at some of the time points

Groups in this outcome

A: Localized Resectable Disease

Stratum A participants had primary tumors potentially resectable by aggressive surgery, such as limb-salvage surgery or amputation, and no evidence of metastasis.

C: Metastatic Tumors

Stratum C participants had metastatic tumors.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
