Correlations between serum ferritin levels and other clinical parameters before PMX-DHP. a: Platelet counts were negatively correlated with serum ferritin levels (r s = −0.839, p = 0.001). b: Serum LDH levels were positively correlated with serum ferritin levels (r s = 0.864, p = 0.001). c: There was no significant correlation between serum ferritin and SP-D levels. d: The P/F ratios were negatively correlated with serum ferritin levels (r s = −0713, p = 0.009). *: p value <0.05
