Table 3 Results of regression analysis on reduction rates. To evaluate the association between removal amount and reduction rate, and to identify cases that fell outside of the association, we performed a regression analysis with reduction rate as the dependent variable and removal amount as the independent variable. The removal amount was log-transformed
