Some reduction in the overall score was seen in the group treated with the IgG-dexamethasone conjugate, but steatosis and hepatocyte ballooning contributing to the NAS was significantly exacerbated in the IgG-dexamethasone group compared to the anti-CD163-dexamethasone group (p = 0.040 and p = 0.004, respectively). Here, CD163 is linked to steatosis.
