Figure 1 Multiple linear regression analysis. A: Self-Rating Depression Scale depression score influencing factors. Forest plot showing the effects of various variables on Self-Rating Depression Scale depression score. Gender (female), age group (young group), and TNM staging (stages III and IV) are all independent risk factors for depression scores. Model statistics: (1) R² = 0.274, adjusted R² = 0.258, F = 16.547, P < 0.001; and (2) All variance inflation factor values < 2.5, no multicollinearity issues; B: World Health Organization Quality of Life Scale Brief Version psychological health domain score influencing factors. Forest plot showing the effects of various variables on World Health Organization Quality of Life Scale Brief Version psychological health domain scores. Dots represent regression coefficient β values, and horizontal lines represent 95%CI. All variables have P < 0.05, indicating statistical significance. Gender (male), age group (elderly group), education level (bachelor's degree and above), and marital status (married) are all protective factors for psychological health. Model Statistics: (1) R² = 0.258, adjusted R² = 0.241, F = 15.247, P < 0.001; and (2) All variance inflation factor values < 2.5, no multicollinearity issues.
