In the present study, age and pre-IVA logMAR VA, pre-IVA levels of MCP-1, MIP-1β, and VEGF, as well as post-IVA logMAR VA and post-IVA levels of IL-6, MCP-1, and MIP-1β were detected as significant factors for predicting the incidence of MA by ROC curve analysis and Kaplan–Meier survival curve. The gene discussed is VEGFA; the disease is microtia.
