We read with interest the article “Fragility Analysis of Statistically Significant Outcomes of Randomised Control Trials in Spine Surgery: A systematic review.”1 The authors utilized fragility index (FI) to assess randomized controlled trials (RCTs) in the spinal surgery literature and concluded that many RCTs are “fragile,” owing to a low median FI score of 2.
