A meta-analysis of 7 independent glioblastoma datasets, consisting of 861 human glioblastoma samples, revealed that PLOD2 was significantly and consistently overexpressed in glioblastoma across all datasets (Figure 1A, Mean Difference IV Random:1.71; CI: 1.23–2.19; P < 0.001). Here, PLOD2 is linked to glioblastoma.
