Note: Bootstrap sample size = 5000. *: denoted the product of two variables, representing the interaction term.
SE: Standard error, LLCI: Lower limit confidence interval 95%, ULCI: Upper limit confidence interval 95%, SD: Standard deviation.
If the number of decimal places is the same as in the previous table, some data cannot be fully displayed, so in this table, the number of decimal places is kept to three decimal places
