Age-adjusted models: overall: n=5780, case mutation positive: n=76, case mutation negative: n=277, control mutation positive: n=566, control mutation negative: n=4861. Multivariable models: overall: n=5749, case mutation positive: n=75, case mutation negative: n=276, control mutation positive: n=564, control mutation negative: n=4834.
