The amount of tissue is in percentage points of the region of interest. All data are displayed as mean ± SD (range), unless otherwise specified. Native samples received the maximum amount of points for score A and B (*). Native samples did not display any unfilled area (§). † P < 0.05 (difference in same group between 3 and 6 months). ‡ P < 0.05 (compared to native)
