Pearson's correlation coefficients for different pairs of measures.

For each pair, the first column provides the Pearson correlation coefficient calculated by using all cancer types, and the second is calculated by using only cancer types whose incidence did not increase during the time period of observation. The quantity d(I) denotes change of incidence rates; d(M) the change of mortality rates; d(S) the change of 5-year survival rates; and d(M/I) the change of mortality over incidence rates, i.e. change of MOI. Significant p-values are indicated by * for P<0.05, ** for P<0.01, *** for P<0.001, + for P<0.0001 and ++ for P<0.00001.
