Mean decrease in pain was 23 (95% confidence interval, -3 to 49) in the test-positive group compared to 11 (95% confidence interval, -6 to 28) in the test-negative group, and mean satisfaction in the test-positive group was 71 (95% confidence interval, 48 to 94) compared to 51 (95% confidence interval, 24 to 78) in the test-negative group.
