CXCR6 and BK-virus nephropathy: Summary of differential gene expression of CXCL16 and CXCR6 in four studies of KTx biopsies with PVAN. Because of the heterogeneity of the data (i.e., one RNA-seq, three microarray), a Cauchy combination method with uniform weights was employed to integrate the p-values across these studies. P-values significant after false discover rate (FDR) correction are bolded and italicized in the Adj. P-value column. Cauchy combined p-values < 0.05 are bolded and italicized.
