This chart shows the 2-year communication impact factor of Transplantation over time and its percentile among journals. Only communications are counted in both the numerator (citations) and denominator (citable items).
How is the 2-year communication impact calculated?
The 2-year communication impact for year X equals the citations received in year X to communications published in years X-1 and X-2, divided by the number of communications published in those two years. Unlike the standard 2-year impact, only items classified as communications are counted in both the numerator and denominator.
