Vоnоprаzаn wаs apprоved compared to placebo in 2023 and is used for non-erosive reflux disease. Investigators would like to conduct a non-inferiority study comparing vonoprazan to omeprazole, a common first line therapy for non-erosive reflux disease. In a prior RCT, the proportion of patients with no heartburn at day 27 was 74% in the omeprazole group and 23% in the placebo group. What is the maximum allowable non-inferiority margin per the FDA guidance? Provide justification for your answer (brief, no more than 1 sentence). (2 points)
