  • a Correlation = 0.719; percentage of agreement = 72.1%; percentage of agreement (±1 year) = 93.6%; κ = 0.472.

  • b From the 465 women for whom we were able to determine whether or not they had a mammogram at KPC within the past 2 years, a total of 32 were excluded from this table because it was impossible to determine the actual time interval since their last mammogram at KPC.
