Fig. 2

Regression coefficients and 95% credible intervals. Regression coefficients (dots) with 95% credible interval (horizontal lines) of the fixed effects of time elapsed since diagnosis and all covariates in the model, for all outcomes. Regression coefficients to the left of the vertical dashed line indicate the parameter is associated with lower values of the corresponding outcome measurement, and conversely for regression coefficients to the right of the dashed line. Some credible intervals are collapsed to 0 (e.g., association between sex and log creatine kinase (CK)), due to there not being any association at all. Abbreviations: sqrt, square root; CMAS, childhood myositis assessment scale; MMT8, manual muscle testing of 8 muscle groups; PGA, physician’s global assessment of disease activity
