Chemotherapy Ward Co-presence Network (IMAGE) NIH/National Human Genome Research Institute Caption This image depicts a chemotherapy ward co-presence network. Circles are patients with color based on when they began chemotherapy (white corresponds to January, 2000, and red corresponds to December, 2008). Patients are connected when they were both in the chemotherapy ward at the same time more than expected by chance.
