Table 7 Results of the Quasi-Poisson Regression Model: Model 2

Dependent Variable	Independent Variable	Coefficients	Standard Error	t Value	p
anonymousNodeNum	Intercept	−1.92	0.014	−136.33	<0.001
	Log(latticeNodeNum)	1.18	0.0015	790.85	<0.001
	domain(ClinicalFinding)	−0.20	0.0059	−34.13	<0.001
	Overall model: residual deviance: 29276 on 5447 degrees of freedom (dispersion parameter for quasi-Poisson family taken to be 4.26)

The variable domain was coded as binary (Procedure/ClinicalFinding).
