| Measurement Characteristic | Melanin | Elastic Fibers |
|---|---|---|
| Preoperative | 0.671 (0.083) | 0.096 (0.014) |
| Six-month postoperative | 0.844 (0.110) | 0.081 (0.042) |
| t value | 4.253 | −0.699 |
| P value | .01 | .52 |
| Melanin AOD/elastic fibers (95% CI) | 0.173 (0.068-0.277) | −0.016 (−0.073 to 0.042) |
Abbreviation: AOD, average optical density (integrated density per unit area).
a
Data are calculated from analyses of AOD for melanin and density for elastic fibers per unit area.
