Note:— – indicates variables that did not show significance on univariable analysis and were not subjected to multivariable analysis.
↵a Ethnicity is included as a variable, as other studies have shown statistically significant differences in the rates of AVM hemorrhage in individuals of different ethnic backgrounds.
↵b Right side considered baseline; test results comparing either left or right to middle were not significant (P = .140).
↵c Tested using ordinal 5-point scale.
