Longitudinal analysis of Hsp90 plasma levels in patients with SSc-ILD treated with cyclophosphamide. (a) No significant differences in plasma Hsp90 were detected between baseline and after 1, 6, and 12 months of therapy with cyclophosphamide in patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD). The red line represents the median. Friedman's test was used for all comparisons. (b) Lower baseline levels of plasma Hsp90 were significantly associated with larger improvement in diffusing lung capacity for carbon monoxide at month 12 from baseline (ΔDLCO% predicted) upon cyclophosphamide treatment. (c) Differences in plasma Hsp90 levels at baseline and one month thereafter in patients grouped according to the course of pulmonary function during the observation time, classified by deterioration and stabilization or improvement of DLCO% predicted at month 12 with respect to baseline. Descriptions of deterioration, stabilization, and improvement are stated in the text. Values are presented as box plots: the boxes represent the 25th–75th percentiles, the lines within the boxes represent the median, and the whiskers represent minimum to maximum.
