Table 2. Expectation and Pain Scores for 2 Expectation Briefing Groups.

Outcome	Adjusted mean (95% CI)		P value
Outcome	Regular expectation briefing (n = 75)	High expectation briefing (n = 77)	P value
Expectation, mean (95% CI)^a	12.58 (11.86-13.31)	12.76 (12.02-13.50)	.60
Pain intensity (mean, 95% CI)^b	4.50 (3.80-5.20)	4.12 (3.39-4.85)	.23

^{^a}

Expectation was measured using the Expectation for Treatment Scale (range, 5-20; higher scores indicate greater expectations for success).

^{^b}

Pain intensity was measured using a numeric rating scale (range, 0-10; higher scores indicate more intense pain).
