Multivariate analysis indicated that there are significant differences (Wilks Lambda P.value = 0.0001, F(4, 71) = 15.26, Value = 0.53) between the two groups of circ_0044234 expression level (low, N = 47 and high, N = 41) at least in terms of one of the dependent variables (histological grade, LMN, Ki67 status, and tumor subtype). This evidence concerns the gene MKI67 and neoplasm.
