Fig 1. The distribution of non-survivors based on the quartiles of absolute neutrophil and lymphocyte counts, and serum CRP and albumin levels in patients with polymyositis/dermatomyositis.

The prevalence of non-survivors increased across quartiles for absolute neutrophil count (ANC, A), and decreased across quartiles for absolute lymphocyte count (ALC, B). Consequently, the prevalence of non-survivors was the largest in the highest quartile of the neutrophil/lymphocyte ratio (NLR, C). Also, the prevalence of non-survivor increased with increasing quartiles of C-reactive protein (CRP, D), and with lower quartiles for albumin (E). Consequently, the distribution of non-survivors was significantly different among CRP/albumin ratio (CAR) quartiles (F). P values were calculated by chi-square test.
