In “ELAPSS score for prediction of risk of growth of unruptured intracranial aneurysms,” the authors established a 6-predictor risk score for aneurysm growth. In their study, they defined significant aneurysm growth as greater than 1 mm. Dr. Willey discusses the possibility of measurement error and bias as a result of this methodology. He also questions whether the readers were blinded, how aneurysm ruptures were treated statistically, and how ELAPSS compares to other existing classification systems. The authors did not respond.
