- **In the study from Jaiswal J, from Bangalore, they separately mentioned anaplastic OGD, anaplastic oligoastroctyoma, and anaplastic astrocytoma; with a separate mention of oligoastrocytoma. Some other studies considered them as mixed glioma or unspecified. So, this part was confusing and a prospective study with WHO 2016 classification may better provide exact prevalence
- &Chawala n et al. quoted 44.18% were grade II while grade III and grade IV constituted 20.9% in their study. The distribution was different as grade IV glioma in other studies were predominant
