Table 2. Results of Cox regression model for additive fixed effects of urbanization and management on survival.

Treatment	Predictor	b*	se	p-value	eb †	95% CI around eb
Control	Management	0.109	0.192	0.569	1.115	(0.766, 1.624)
	Urbanization	1.409	0.491	0.004	4.093	(1.562, 10.722)
Paraquat	Management	0.021	0.073	0.769	1.021	(0.886, 1.177)
	Urbanization	0.407	0.176	0.021	1.502	(1.063, 2.123)

*b is the regression coefficient of each variable.

^†e^b is interpreted as the multiplicative effect of the hazard (e^b = 1 indicates no hazard; e^b < 1 indicates decreased hazard; e^b> 1 indicates increased hazard)
