Correlation between husbands and wives on a waist circumference, and b body mass index. Each dot represents one pair of a husband and his wife. The line in the middle is a calculated regression line and dotted lines on both sides show the 95 % ranges. The regression line for a is Y = 647 + 0.15X [where X and Y are waist circumference (in cm) for husbands and wives, respectively] (r = 0.146, p < 0.01) and the line for b is Y = 18.5 + 0.12X [where X and Y are body mass index (in kg/m2) for husbands and wives, respectively] (r = 0.128, p < 0.01)
