Bar chart showing the responses to the question ‘How do you manage patients with severe symptoms on first presentation (limits daily activity)?’ for the subgroup of 23 surgeons who routinely perform femoroacetabular impingement (FAI) surgery and who would be willing to recruit patients into a randomised controlled trial. The three digits of the surgical equipoise ratio (SER) represent the sum of the scores within the range ‘-5 to -1’, followed by scores of ‘0’, followed by scores within the range ‘+1 to +5’.
