Survival analysis of erythroleukemic mice treated with neutralizing antibody against VEGF-A. Erythroleukemic mice were randomized and divided into 3 groups: (1) control untreated group (solid line); (2) group treated with goat IgG as a control (data not shown); or (3) a group treated with a neutralizing antibody against VEGF-A (dotted line) for 2 weeks. Mice were monitored on a daily basis and killed according to institutional guidelines, and survival was assessed by the method of Kaplan-Meier. Dotted horizontal lines represent median survival.
