CCL24 and posterior cortical atrophy: Based on the important role of CXCL14, CCL20, CCL24, and CCL26 in PCa, the CRPGS was established by using the LASSO-Cox regression, which was as follows: riskscore = (CXCL14 expression * 0.185018842290928) + [CCL20 expression * (-0.408867899574549)] + (CCL24 expression * 0.280649328317824) + (CCL26 expression * 0.33033065384401).
