A retrospective, non-interventional, single-center study conducted in Spain, based on the collection of data from the medical histories of patients with Familial Mediterranean fever (FMF) diagnosed during childhood from January 2005 to December 2021.
Data from the patients' medical records was collected retrospectively, from the time of diagnosis to the current moment of the patient's enrollment in the study. Patients had a minimum follow-up of 3 months after diagnosis.

| Autoinflammatory Disease Activity Index (AIDAI) Score | The AIDAI is an assessment tool used to evaluate the level of disease activity. The AIDAI for FMF includes 7 variables: fever, abdominal pain, chest pain, arthralgia or myalgia, swelling of the joints, skin rash, and pain relief taken. Disease activity scores are calculated from the daily scores collected in a patient diary completed during flares. Fever is scored as 0 (absent) or present (1), with all other clinical variables scored from 0 (absent) to 3 (severe). Pain relief taken is not included in the disease activity score calculation. A higher total score indicates a higher level of disease activity. AIDAI was used to assess the association between disease activity and colchicine resistance/intolerance, response to canakinumab treatment, pain, fatigue, and quality of life (absenteeism at school during flares, limitation of physical activity, psychological care, and overall health status). | Up to 11 years |
| Autoinflammatory Disease Damage Index (ADDI) Score | The ADDI is an assessment tool used to evaluate the level of damage caused by autoinflammatory disease. It consists of 18 damage items grouped by organ system: reproductive, renal/amyloidosis, developmental, serosal, neurological, ears, ocular and musculoskeletal damage. Each damage item is defined and assigned a score of 1, 2, or 3, with each organ system having a maximum allowed score. A higher total score indicates a higher level of damage. ADDI was used to assess the association between disease damage and colchicine resistance/intolerance, response to canakinumab treatment, pain, fatigue, and quality of life (absenteeism at school during flares, limitation of physical activity, psychological care, and overall health status). | Up to 11 years |
| Familial Mediterranean Fever 50 (FMF50) Score | The FMF50 is an assessment tool used to evaluate response to treatment for FMF. It consists of 6 items:
FMF50 was used to assess response to canakinumab treatment and the association between response to treatment and colchicine resistance/intolerance, pain, fatigue, and quality of life (absenteeism at school during flares, limitation of physical activity, psychological care, and overall health status). | Up to 11 years |
| Number of Patients by Last Response Reported to Anti-IL-1 Treatment During the Study | Responses included:
Anti-IL-1 treatments included canakinumab and anakinra. | Up to 11 years |

| Up to 11 years |
| Visual Analogue Scale (VAS) Score From Clinician Point of View | Patients' overall state of health was assessed using VAS scoring. The VAS is a straight line with a scale ranging from 0 (worst health) to 10 (best health). The clinician marks a point on the line, scoring how they perceive the patient's overall state of health. VAS was used to assess the association between anti-IL-1 treatment response and overall state of health. Anti-IL-1 treatments included canakinumab and anakinra. Treatment response was categorized as follows:
| Up to 11 years |
| Visual Analogue Scale (VAS) Score From Patient Point of View | Patients' overall state of health was assessed using VAS scoring.
