Thomson Reuters has released its 2015 Science Edition of the Journal Citation Reports, which gives journal impact factors and rankings of approximately 8,000 science journals. The 2014 impact factors of APS journals, along with a comparison of the past 4 years, are given in the table below. The table also shows the rank of APS journals in the physiology category, as well as each journal’s cited half-life.

Comprehensive Physiology experienced the largest increase, up to 4.739 from 1.685 a year ago. Other journals with increased impact factors are AJP-Lung (4.080), AJP-GI (3.798), and AJP-Cell (3.780). Physiological Reviews retains the top spot in the field of physiology at 27.324 (24,528 citations).

The 2015 Journal Citation Reports includes an update to the Five-Year Impact Factor and Eigenfactor™ Metrics in JCR Web. Eigenfactor™ Metrics use citing journal data from the entire JCR file. The Eigenfactor™ score and the Article Influence™ score are calculated based on the citations received over a five-year period.
