E1690 | R Documentation |
A data set from the ECOG E1690 trial evaluating the effectiveness of the interferon alfa-2b (IFN) therapy compared to the observation in high-risk melanoma patients. There were three arms in the trial: high-dose IFN, low-dose IFN, and observation. The study results were described in Kirkwood et al. (2000) doi:10.1200/JCO.2000.18.12.2444. Here, we only consider the high-dose IFN arm and the observation arm so that this data set has the same variables as the E1684 data set. We can use the E1684 data as the historical data and the E1690 data as the current data.
