Medical records 

Hospital records​ are valuable sources of clinical data that can support research on the effects of chemotherapy on neurogenesis. These records provide detailed patient information, including chemotherapy regimens, dosages, treatment durations, and clinical outcomes. By reviewing patient histories, researchers can identify individuals who have undergone specific chemotherapy treatments and correlate these data with neurological outcomes or biomarkers related to neurogenesis.

Using hospital records ensures access to real-world clinical information, enhances the relevance of the research findings, and allows comparison between treated and control groups. Strict ethical standards and patient confidentiality must be maintained, with appropriate approvals obtained from institutional review boards or ethics committees before accessing or using patient data.
