Comparison of pain at different thresholds between the control and intervention groups with two different hypotheses about the missing data.
| Pain Intensity 1 | Control Group n (%) |
Intervention Group n (%) |
Unadjusted Difference [95% CI] |
p-Value |
|---|---|---|---|---|
| Pain intensity > 3 | 30 (31%) | 16 (14%) | −17% [−27 to −5%] | 0.022 |
| Pain intensity > 5 | 14 (15%) | 5 (5%) | −10% [−18 to −1%] | 0.03 |
| Pain intensity > 7 | 2 (2%) | 0 (0%) | −2% [−7 to 3%] | 0.22 |
1 Pain intensity measured using a numerical scale from 0 to 10; where 0 is no pain; 1 to 3 corresponds to mild pain; 4 to 6 corresponds to moderate pain; 7 to 10 corresponds to severe pain.
