In univariate Cox regression using continuous values, higher FAP expression (HR = 1.01, p = 0.03, corrected P value = 1.00) and higher SPARC expression (HR = 1.07, p = 0.006, corrected P value = 0.21) in tumor stroma were associated with shorter survival in MPM patients (Figure 2A–D). Here, FAP is linked to neoplasm.
