Coefficients	Estimate	Std. Error	z-value
Intercept	−3.54	0.69	−5.14	2.7e-07
rHBPs	2.51	0.62	4.08	4.54e-05
BCS	2.02	0.60	3.40	0.0007

Null deviance: 30.63 on 3 degrees of freedom.

Residual deviance: 1.5 on 1 degree of freedom.

Akaike Information Criterion (AIC): 17.8.

rHBPs = recombinant heparin binding proteins, 0 or 1 for the treatment or control group, respectively.

BCS = body condition score, 0 or 1 for BCS = 4 or 6, respectively.
