The results of the meta-analysis were not affected by the omission except VEGF rs699947, and VEGF rs1570360 which became insignificant, and CTLA-4 rs231775, which showed a significant association with osteosarcoma after the omission which is consistent with having a race effect since all the remaining papers reported on the association in the Chinese population. Here, CTLA4 is linked to osteosarcoma.
