2015年6月18日，備受關注的湯森路透《SCI期刊分析報告》新鮮出爐。該報告涵蓋了來自82個國家的237個大類的11149本期刊。本年度有272本雜誌第一次被收錄;與去年相比，53%的雜誌影響因子增加。Ca-Cancer J Clin、NEJM以及CHEM REV再次包攬了榜單的前三甲，影響因子分別為115.84、55.873、 46.568。
與去年相比，排在前十名的雜誌中出現兩位新成員，一個是排在第5位的NATURE REVIEWS DRUG DISCOVERY，影響因子41.908，去年該雜誌排在第11位，影響因子為37.231;另一個是排在第9位的NATURE REVIEWS MOLECULAR CELL BIOLOGY，影響因子為37.806，去年排在第12位，影響因子為36.458。
備受矚目的《柳葉刀》雜誌今年排到了第4位，影響因子45.217，較去年上升了4個名次(去年影響因子39.207)。Nature、Science、Cell分別排在第7、16和20位，對應的影響因子為41.456、33.611、32.242。與去年相比，Nature下降了2個名次、Science上升了1個名次、Cell下降了4個名次。
此外，今年Nature雜誌有兩個子刊排在了主刊的前麵，除了上述前十的新成員NATURE REVIEWS DRUG DISCOVERY，還有排在第6的NATURE BIOTECHNOLOGY，影響因子為41.514，該雜誌去年排在榜單的第9位，影響因子為39.08。
影響因子在一定程度上是一本雜誌質量高低的標準之一，並且能夠帶來科學以外太多的東西：教職、基金申請、學術影響力等。盡管很多學者批評過雜誌影響因子，但是取消或者改革不是短時間就能實現的事情。以下列舉排在前50位的雜誌最新的影響因子：
