Forest plot of overall survival in high risk patients treated with adjuvant interferon-α (IFN-α). Overall survival among patients with high-risk melanoma was improved with IFN-α adjuvant therapy compared to control (p < 0.03; odds ratio = 0.88; 95% CI = 0.79–0.99). Treatment improved overall survival compared with control regardless of dose or pegylation of the adjuvant IFN.

Abbreviations: CI, confidence interval; N, total number of patients per group; n, number of patients with disease progression.
