Note. Significant simple effects of Time within Cluster and Member are denoted by asterisks, and the pairwise contrasts of time are shown in column 4. Significant differences between husband and wife within cluster and time are denoted by superscripts, with means with an “a” superscript being significantly higher than means with a “b” superscripts.
