Table 2 Graft volumes and volumetric change rates for both groups.
| Groups | N | V1, mean±SD | V2, mean±SD | Volumetric change rate*, mean±SD |
|---|---|---|---|---|
| Control | 26 | 1.82±0.78 cm | 1.62±0.72 cm | 12.76±5.45% |
| Test | 28 | 1.77±0.81 cm | 1.61±0.76 cm | 10.22±4.37% |
| P value | 0.793 | 0.956 | 0.069 | |
| SD – standard deviation; V – graft volume immediately after surgery; V – graft volume at 6 months after surgery. * Volumetric change rate=(V–V)/V×100%. | ||||
