Multiple linear regression model for the mental domain of the quality of life. Only significant predictors are presented in the table.

Variables	R^2	Unstandardised coefficients		p	95% CI for β
		β	Std. error		Lower bound	Upper bound
	0.375
KPSS		0.35	0.06	≤0.001	0.240	0.465
Total symptoms number		−1.48	0.17	≤0.001	−1.81	−1.15

COPD diagnosis		−6.52	1.6	≤0.001	−9.67	−3.37

All values are significant at the conservative level of ≤0.05. KPSS = Karnofsky Performance Status Scale; COPDs = chronic obstructive pulmonary diseases.
