Table 3. Comparison of the complete remission rate of vomiting (CR) between the two groups in each stage.
| Study endpoint | Megestrol group (n=60), n (%) | Control group (n=60), n (%) | RR (95% CI) | χ2 | P |
|---|---|---|---|---|---|
| Delay period (24–120 h) | 46/60 (76.7) | 31/60 (51.7) | 1.586 (1.179–2.134) | 10.276 | 0.001 |
| Acute phase (0–24 h) | 49/60 (81.7) | 47/60 (78.3) | 1.043 (0.872–1.247) | 0.208 | 0.648 |
| Overall period (0–120 h) | 41/60 (68.3) | 28/60 (46.6) | 1.464 (1.063–2.018) | 5.763 | 0.016 |
| Proportion of grade, 3–4 vomiting | 0/60 (0) | 6/60 (10.0) | 1.107 (1.021–1.210) | 6.107 | 0.013 |
P value was calculated by χ2 to test the rate of no vomiting (CR). CI, confidence interval; CR, complete remission rate; RR, risk ratio.
