Comparative Analysis of Postoperative CRP Levels in Patients with and Without Complications During Days 1–3 and 4–7 Following Rectal Cancer Surgery—This box plot illustrates the comparison of CRP levels on postoperative days 1–3 and 4–7 between patients experiencing complications and those without complications. Initial CRP levels (Days 1–3) were comparable; however, patients with complications exhibited significantly higher CRP levels on Days 4–7, indicating this later timeframe as crucial for monitoring (p = 0.000045).
