Figure 4. Standardized regression coefficients of parameters in optimal multiple linear regression models. Fat score residual was set as the dependent variable, responding to predictors in (A) on the capture day, (B) three days before capture day, and (C) seven days before capture day. Bars represent the 95 % confidence interval of the coefficients, and the color of the bar represents the classification of factors (red to inner factors, blue to external factors.) Signif. codes: 0 ‘***’, 0.001 ‘**’, 0.01 ‘*’, 0.05 ‘.’.
