Summary of the Effect of CCX140-B Treatment on Quality of Life Endpoints SF-36V2 for the overall trial SF-36v2: Medical Outcomes Survey Short Form-36 version 2. SF-36v2 measures each of the following eight health domains: Physical Functioning, Role-Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role-Emotional, and Mental Health. Scores on each item are summed and averaged. The SF-36v2 component domain scores range from 0 (worst health) to 100 (best health).

Summary of the Effect of CCX140-B Treatment on Quality of Life Endpoint EQ-5D-5L for the overall trial EQ-5D-5L: EuroQuality of Life-5 Domains-5 Levels. The EQ-5D-5L consists of : the EQ-5D descriptive system. The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The scale is numbered from 0 to 100. 100 means the best health you can imagine. 0 means the worst health you can imagine.
