Similar Clinical Outcomes of Early and Late Anti-TNF Initiation for Ulcerative Colitis: A Nationwide Population-Based Study

The optimal timing of anti-tumor necrosis factor (anti-TNF) initiation in patients with ulcerative colitis (UC) remains unclear. Very little is known about the clinical outcomes after the early versus late initiation of anti-TNF therapy, especially in Asian UC patients. Here we aimed to assess whether earlier anti-TNF treatment initiation results in favorable clinical outcomes in Korean UC patients.Using the Korean National Health Insurance...
