|---|---|---|---|---|
| 30 (n = 11a) | 3.22 ± 3.90 | 21.3 ± 7.05 | 62.7 ± 12.9 | membranes mostly broken/separated some membranes isolated due to cellular activity isolated degradation regions along strut edges |
| 60 (n = 12a) | 6.91 ± 4.97 | 48.4 ± 8.53 | 63.7 ± 11.4 | membranes are mostly degraded with the rest broken and/or isolated due to cellular activity or tissue ingrowth increased number of degradation regions per strut as well as increased number of struts with degradation regions |
| 90 (n = 17a) | 9.42 ± 7.05 | 64.3 ± 13.9 | 59.1 ± 12.9 | majority of membranes are degraded; remaining are broken or isolated continued increase in number of degradation regions and number of struts presenting degradation (scalloping pattern) |
