Risk factors of progression from discoid lupus to severe systemic lupus erythematosus: a registry-based cohort study of 164 patients.

In our article entitled "Risk factors of progression from discoid lupus to severe systemic lupus erythematosus: a registry-based cohort study of 164 patients", we studied risk factors of progression from discoid lupus (DLE) to severe systemic lupus (SLE) and developed a score that could predict this progression. Here, are presented our supplemental data. Supplementary Table 1 reports a literature review concerning risk factors for progression to SLE in patients with DLE or cutaneous lupus. Supplementary Figure 1 and 2 present the performance of the score presented in the article among patients with isolated DLE and patients with DLE associated to mild SLE.
