Table 3.

Comparison of mean titration size between types of procedures, in mcg•kg^-1•min^-1.

Type of Procedure	Mean	Standard Deviation
Catheterization	2.35	1.79
Craniofacial	1.25	0.76
Spinal	1.12	0.67

Procedure Comparison	Difference Between Means	95% Confidence Limits
Catheterization - Craniofacial	1.09**	0.22	1.96
Catheterization - Spinal	1.22**	0.36	2.08
Spinal - Craniofacial	−0.13	−0.45	0.19

The 3 types of procedures were compared using ANOVA. The mean titration size in each is shown in the top half of the table. Scheffe's test was used to compare the mean titration size among catheterization, craniofacial, and spinal procedures, shown in the lower half of the table. Asterisks indicate a statistically significant difference in the 2 groups' means, p=0.0023.
