*
Agreement was defined as if the dietary intake of a child and his or her mother’s was in the same quartile, e.g., both were in the top quartile.
†
The % of agreement by chance (random) was 25%.
¶
Kappa measured the agreement based on quartile positions beyond that by chance; k>0.2 suggests agreement; and k>0.4 suggests moderate agreement.
