Table 3. Associations Between Expectation Accuracy and Health-Related Quality of Life Over Time.

Measure	Linear regression estimate (95% CI)^a
Measure	3 mo	12 mo	24 mo
Baseline health-related quality of life	0.78 (0.69 to 0.87)^b	0.79 (0.69 to 0.89)^b	0.76 (0.63 to 0.90)^b
Positive emotion expectation accuracy	1.05 (−0.37 to 2.47)	0.52 (−1.02 to 2.06)	0.18 (−1.79 to 2.14)
Negative emotion expectation accuracy	−3.04 (−4.78 to 1.29)^b	−1.28 (−2.99 to 0.44)	−2.39 (−4.67 to 0.12)^c
Dyspnea expectation accuracy	4.68 (2.68 to 6.68)^b	2.41 (0.45 to 4.37)^c	3.21 (0.82 to 5.60)^d
