Table 4.
Cough scores and corresponding between-groups mean differences at visit 1–4 in patients with (SPC+) or without (SPC−) somatic points for cough.
| Cough score |
||||
|---|---|---|---|---|
| SPC+ | SPC− | Mean difference | p value | |
| Visit 1 | 5.70 (5.28, 5.80) | 5.01 (4.90, 5.64) | 0.65 (−0.21, 0.81) | 0.044 |
| Visit 2 | 3.43 (3.17, 3.70) | 2.74 (2.47, 3.05) | 0.69 (0.07, 1.28) | 0.0149 |
| Visit 3 | 3.19 (2.83, 3.55) | 1.91 (1.54, 2.28) | 1.28 (0.48, 2.08) | <0.0001 |
| Visit 4 | 2.94 (2.44, 3.44) | 0.97 (0.39, 1.56) | 1.97 (0.78, 3.16) | <0.0001 |
Values are estimated means and 95% Confidence Interval (CI) from mixed-model repeated measures analyses adjusted for cough score at V1. Including the sex as an additional covariate in the models did not change the outcomes.
