Outcome measures: therapeutic inertia, lack of treatment initiation, and lack of treatment escalation

Variables	TI score			TI score for treatment initiation			TI score for treatment escalation
	β	95% CI	p value	β	95% CI	p value	β	95% CI	p value
Age ≥ 40 years	1.53	− 0.51, 3.11	0.057	1.78	0.31, 3.25	0.019	0.71	− 0.43, 1.84	0.21
Years of experience	− 0.077	− 0.16, 0.008	0.073	− 0.085	− 0.16, − 0.007	0.035	− 0.043	− 0.10, 0.017	0.15
Ambiguity score	− 0.44	− 0.83, − 0.049	0.029	− 0.46	− 0.82, − 0.098	0.015	− 0.35	− 0.62, − 0.065	0.018
Overall expectation with treatments	− 0.049	− 0.084, − 0.013	0.009	− 0.048	− 0.081, − 0.015	0.006	− 0.036	− 0.06, − 0.011	0.007

Derived from linear regression analysis adjusted for all presented variables. Age was dichotomized by the median split because there was collinearity between age and years of experience (variance inflation factor < 3)

Note the consistency of results showing that lower aversion to ambiguity and lower expectation of treatment response were associated with higher TI score, TI in treatment initiation and TI for treatment escalation after adjustment for participants’ age and years of experience
