The other four causal inferences were consistent with the MR results between gut microbiota and prostate cancer: G_Ruminococcus2 (ebi-a-GCST90017063)/neurturin levels (NTRN, GCST90274828)/prostate cancer, G_Anaerofilum (ebi-a-GCST90016965)/TNFRSF14 (GCST90274842)/prostate cancer, G_Ruminococcaceae UCG014 (ebi-a-GCST90017061)/TNFSF10 (GCST90274843)/prostate cancer, and G_Erysipelotrichaceae UCG003 (ebi-a-GCST90016994)/TNFSF10 (GCST90274843)/prostate cancer. Here, TNFRSF14 is linked to prostate cancer.
