Fibrosis ratio by time
| Group | 14 Days | 1 Month | 3 Months | 6 Months |
|---|---|---|---|---|
| PA (n = 18) | 0.2 | 1.4 | 10.3 | 28.6 |
| FBC (n = 18) | 1.2 | 1.2 | 17 | 15.1† |
| Ad-BMP-13 (n = 20) | 0.7 | 29.5* | 62.2* | 45.1† |
Note:—PA indicates the bare platinum coil group; FBC, fibroblast-coated platinum coil group; Ad-BMP-13, bone morphogenetic protein-13 gene transfected fibroblast-coated coil group.
* Variable is significantly different from other groups (P < .05) at 4 weeks and 3 months.
† Difference among groups is significant (P < .05) at 6 months.
