The effect of infective Dose and Time p.i. on the concentration of IL-4 and IL-13 by mesenteric lymph node cells stimulated with parasitic female antigen

	Term	Coefficient	χ2	P-value
IL-4a	Constant	−5.52 ± 1.36
	Time	0.265 ± 0.067	13.87	0.0034
	ln Dose	1.35 ± 0.18	43.37	<0.0001
IL-13b	Constant	2.08 ± 2.05
	ln Dose	5.26 ± 0.486	60.15	<0.0001

All P-values are Bonferroni corrected.

^a2 × log-likelihood = 167.5, χ² = 48.64, P < 0.0001.

^b2 × log-likelihood = −269.2, χ² = 60.15, P < 0.0001.
