Schematic representation of the study design to identify structural parameters in the tubulointerstitium (TubInterstitium) that coexpress with long-term clinical outcomes. In step 1, modules or groups of genes with similar expression profiles are constructed from the transcriptome profile using a weighted gene coexpression analysis (WGCNA) strategy. In step 2, a module eigengene (ME) is derived from each module and associated with clinical and structural parameters (ACR, albumin-to-creatinine ratio; iGFR, iothalamate glomerular filtration rate; VvInt, cortical interstitial fractional volume). The heat map table illustrates the correlation coefficients of the ME and the tested parameters. The significant modules (marked by *) are then further investigated for functional enrichments (GO, gene ontology). Reprinted with permission from Nair et al. (85).
