New journal selection for quantitative survey of infectious disease research: application for Asian trend analysis.

abstract：BACKGROUND:E1684 was the pivotal adjuvant melanoma trial for establishment of high-dose interferon (IFN) as effective therapy of high-risk melanoma patients. E1690 was an intriguing effort to corroborate E1684, and the differences between the outcomes of these trials have embroiled the field in controversy over the pas...
