In total, 756 couples were subjected to analyses. For abbreviations, see Table 4. The intercepts (α) and slopes (β) are in the regression equation of Y = α + βX, where X and Y are the values for husbands and wives, respectively. Partial correlation coefficients are for correlation between husbands and wives, taking three variables of the item for husbands, that for the wives and the average ages of each husband and wife pair
^a p for correlation coefficients or partial correlation coefficients.
**, * and ns stand for p < 0.01 (r > 0.093), p < 0.05 (r > 0.071) and p ≥ 0.05, respectively. For basis of evaluation of p values, see “Statistical evaluation” in the “Subjects and methods” section
^bAfter logarithmic conversion
^cMS, RES and NonMS are given scores of 3, 2 and 1, respectively
