hereditary hemochromatosis type 1: Hemochromatosis type 1 (classic) is the most common form of hereditary hemochromatosis (HH), a group of diseases characterized by excessive tissue iron deposition. Due to its incidence (1/200-1/1000), it is not considered as a rare disease, unlike the other subforms of the disease

CodeWAS (R11)
↥CodeWAS is a tool for exploring the associations between an endpoint and all of the medical codes and drug codes.
This is a new tool, please reach out using the contact form for feedback and improvement ideas.
First, a cohort is built by matching controls to the endpoint cases using year of birth and sex. Then, a Fisher test is done for all the medical codes and drug codes between the cases and controls of this cohort. Codes are reported in the table below if they have −log10(p-value) ≥ 6.
