We examined eligibility criteria from recent oncology clinical trials to see whether real-world data (RWD) from electronic health records (EHRs) could be used to create external control groups for clinical trials. Trials were identified from the Aggregate Analysis of ClinicalTrials. gov database; the selected trials were for oncology drugs approved by the FDA in 2020. https://parisnaturalfoodes.shop/product-category/l-glutamine/
