However, the prespecified sensitivity analysis, in which adhesions were classified in three clinically meaningful categories: no adhesions (grade 0), thin/mild adhesions (grades 1–2) and thick/severe adhesions (grades 3–4), revealed a marginally statistically significant difference between the groups (Pearson χ 2 = 9.578, df = 4, exact p = 0.037), allowing for a clearer comparative assessment ( Table 4 ) (Supplementary File S1) .
