Prognostic survey participation profile. RMSP, rheumatic musculoskeletal pain. The prognostic survey cohort sample was issued from the TELECHIK survey, a population-based cohort study (November 2007 to May 2008) (23). After elimination of 582 Chikungunya virus (CHIKV)-seronegative subjects and 90 subjects not presenting with RMSP at disease onset, 76 subjects were excluded (50 children, 15 adults for relocations and absence of contact, 11 for the absence of overt temporality in the clinical course of Chikungunya rheumatism), leaving 346 eligible adult participants assessed on the course of RMSP. This population was shifted towards the selection of more women and older participants.
