Linear regression analysis indicates that CD163 and OAS1 expression are coordinately expressed (P = 0.0004, R2 = 0.6019) and two way ANOVA analysis confirms that leprosy type of the lesion is significantly (P = 0.0003) associated with differential gene expression of CYP27B1, CD163 and OAS1 (Fig 3C). Here, OAS1 is linked to leprosy.
