Table 3. Results of the meta-analysis of the tumor inhibition outcome index.
| Outcome indicator | Number of studies | Sample size T/C | MD/SMD | 95% CI | I2/% | P value |
|---|---|---|---|---|---|---|
| Tumor weight (g) | 22 | 191/189 | MD =−0.94 | −1.10, −0.79 | 98 | <0.05 |
| Tumor volume (cm3) | 11 | 67/67 | MD =−0.78 | −1.06, −0.50 | 99 | <0.05 |
| Tumor number (pcs) | 7 | 74/72 | SMD =−3.27 | −4.30, −2.23 | 73 | <0.05 |
g, gram; cm3, cubic centimeter; pcs, pieces. T represents the intervention group, C represents the control group. MD, mean difference; SMD, standardized mean difference; CI, confidence interval.
