Table 4.

Combination index values of Cry5B and nAChR agonists at different effect dose (ED) levels (e.g., at the combination dose at which 50 % of the C. elegans roundworms are killed, Cry5B and levamisole show a combination index value of 0.38)

Combinations	Combination index value^a
Combinations	ED₅₀	ED₇₅	ED₉₅
Cry5B + tribendimidine	0.52	0.30	0.12
Cry5B + levamisole	0.38	0.26	0.15
Cry5B + pyrantel	0.64	0.54	0.40

From (Hu et al. 2010b)

Combination index values <1 are indicative of synergy. The combination index values shown here are generally indicative of strong synergy
