Effect of a T6'S mutation on inhibitor pIC₅₀ values

Agonist	ΔpEC₅₀	P (H₀: ΔpEC₅₀=0)	pEC₅₀^{^a}
5-HT	0.35 ± 0.07	3 × 10⁻⁶	6.00 ± 0.08
Inhibitor^{^b}
Citral	−0.36 ± 0.10	0.002	3.55 ± 0.11
Eucalyptol	−0.45 ± 0.22	0.046	3.14 ± 0.05
Linalool	−0.34 ± 0.04	5 × 10⁻⁷	3.51 ± 0.24

↵^a Standard errors were calculated from the errors of the pEC₅₀/pIC₅₀ and ΔpEC₅₀/ΔpIC₅₀ values using propagation of error calculations.
↵^b There was no significant difference between the ΔpIC₅₀ values for the three inhibitors (P = 0.87).
