AQP5 and neoplasm: We then generated a prediction equation for NIFTP using a logistic regression analysis of these four mRNAs to assess their capacity to distinguish NIFTP from other tumor types: prediction score = −3.722 + (9.950 × expression level of OCLN) + (70.667 × expression level of ZNF423) - (273.325 × expression level of LYG1) + (2.752 × expression level of AQP5).
