Figure 1. Adhesion coverage at 30 days compared with coverage at the 90-day follow-up assessment. Values are median (interquartile range). At 30 days: *p < 0.050 versus Strattice and Parietex composite; §p < 0.050 versus all other meshes; ±p < 0.050 versus all other meshes. At 90 days: ❖p < 0.050 versus Permacol and Prolene; ◉p < 0.050 versus Permacol and Prolene. At 90 days, Prolene, Strattice, and Permacol showed a signi cant reduction compared with their status at 30 days (Mann–Whitney U test).
Mesh incorporation
At 30 days, no signi cant di erence in mesh edge incorporation was seen between Parietex composite (70 %; IQR, 53–80 %), Prolene (50 %; IQR, 46.3– 56.1 %), Surgisis (34 %; IQR, 16.7–66.5 %), Strattice (23 %; IQR, 5–70 %), and Permacol (48 %; IQR, 34.3–69.6) meshes. At 90 days, the percentage of Parietex composite mesh incorporated (79 %; IQR, 61.2–83.0 %) was signi cantly higher than that of Prolene (53 %; IQR, 31.0–61.2 %), Strattice (40 %; IQR, 9.5– 57.4 %), or Permacol (21 %; IQR, 16.0–41.4). The percentage of Surgisis mesh edge incorporated was 66 % (IQR, 0–100 %). Five meshes showed complete incorporation, whereas two other meshes did not incorporate at all (Figures 2 and 3). For each mesh, no signi cant di erences were observed between 30 and 90 days.
