95% confidence limits for a quoted correlation coefficient

Quoted correlation coefficient	Lower limit n = 4000	Upper limit n = 4000	Lower limit n = 1333	Upper limit n = 1333
+0.000	-0.032	+0.032	-0.055	+0.055
+0.100	+0.069	+0.131	+0.045	+0.154
+0.250	+0.220	+0.279	+0.198	+0.301
+0.400	+0.373	+0.426	+0.353	+0.445
+0.800	+0.788	+0.811	+0.779	+0.819
+0.900	+0.894	+0.906	+0.889	+0.910
+0.950	+0.947	+0.953	+0.944	+0.955

The limits are 95% confidence intervals which have been calculated from the Fisher transformation as plus or minus two times the standard error.
