Evaluation of the robustness of randomized controlled trials for the treatment modalities of esophageal cancer using the fragility index - a systematic review.

Background: Esophageal cancer remains a significant global health challenge. Several treatment modalities were explored in randomized controlled trials (RCTs) in recent decades. This study evaluates the robustness of RCTs focusing on esophageal cancer treatment using the fragility index (FI) and reverse fragility index (RFI).
