title: Carriers and noncarriers of haemophilia A. Evaluation of bleeding symptoms registered by a self-administered questionnaire with binary (no/yes) questions.
abstract: Carriers of haemophilia A were recently described to have significantly more bleeding symptoms than healthy females. Eighteen obligate carriers and 20 females classified as carriers with approximately 95% confidence, as described in an accompanying paper, were compared with 56 noncarriers with respect to ten bleeding symptoms, registered by a questionnaire. A rank-order of negative findings indicating noncarrier state is presented, as well as a rank order of positive findings indicating carrier state. A summation index of the total diagnostic capacity of the ten questions shows that carriers have more bleeding symptoms than healthy females.
