ABCA1 and prostate adenocarcinoma: Finally, by weighting the relative infiltrating level of each tumor‐infiltrating immune cells to its regression coefficient, we established an IPM to predict the prognosis of PRAD patients (risk score = 0.6769 × relative infiltrating level of MDSC + 0.6472 × relative infiltrating level of pDC + 0.5369 × relative infiltrating level of T helper cells−0.6389 × relative infiltrating level of the Tgd–0.8783 × relative infiltrating level of Th1 cells).
