^†Statistical tests examine the null hypothesis that people with haemophilia A have the same costs of care as people with haemophilia B.

^‡Statistical tests examine the null hypothesis that people who receive bypassing agents have the same costs of care as people who do not receive bypassing agents.

^§Statistical tests examine the null hypothesis that the costs of clotting factor for people who receive bypassing agents are the same as those for people who do not receive bypassing agents.

^¶Statistical tests examine the null hypothesis that children have the same costs of care as adults.
