↵a Percentages refer to the number of patients with non-missing values (46 clip and 48 coil). P values are from the likelihood ratio test using propensity scores and odds ratios, and resulting 95% CIs are derived from the logistic model that includes both treatment and propensity scores (see “Materials and Methods” section).
