The WBC count (p = 0.007), aspartate transaminase concentration (p = 0.045), alanine transaminase concentration (p = 0.039), and LDH concentration (p = 0.019) were significantly higher in the RP-ILD group than in the non-RP-ILD group, whereas the lymphocyte count (p < 0.001), albumin concentration (p = 0.005), and PNI (p < 0.001) were significantly lower in the RP-ILD group than in the non-RP-ILD group. This evidence concerns the gene ALB and retinitis pigmentosa 1.
