Before real world data (RWD)-derived external control arms (ECAs) can be applied in clinical trials within the field of oncology, it must be determined whether these ECAs can function as appropriate and reliable control arms. This review provides an overview of studies in which RWD-derived ECAs were constructed and compared to a randomized clinical trial (RCT) arm. RWD-derived ECAs had similar survival outcomes as the RCT arm of comparison in six of the eight included studies. Therefore, when performing RCTs is not feasible, RWD-derived ECAs can act as control arms in single-arm clinical trials, provided that suitable RWD sources are used and suitable methodological decisions are made.

Background: Processing data from electronic health records (EHRs) to build research-grade databases is a lengthy and expensive process. Modern arthroplasty practice commonly uses multiple sites of care, including clinics and ambulatory care centers. However, most private data systems prevent obtaining usable insights for clinical practice.

Background: Breast cancer is the second most common cancer in women worldwide. Treatments for this disease often result in side effects such as pain, fatigue, loss of muscle mass, and reduced quality of life. Physical exercise has been shown to effectively mitigate these side effects and improve the quality of life in patients with breast cancer.

Malaria control in highly endemic regions relies heavily on vector control tools, particularly LLINs. The effectiveness of LLINs varies by eco-epidemiological conditions and brands. A comprehensive review of WHO interim-approved LLIN brands is necessary to address this variability.

Kindling is an experimental-induced seizure consistent with epilepsy disease, a chronic neurological disorder characterised by spontaneous and repeated seizures. This disease is associated with oxidative stress, and most therapeutic strategies against epilepsy aim at improving the antioxidant defence mechanism in the brain. However, prolonged usage and associated adverse side effects limit antiepileptics, warranting natural antioxidant patronage.

The fall armyworm (FAW), Spodoptera frugiperda, is a serious invasive crop pest and threat to food security. Conventional pest control approaches using chemical pesticides can lead to adverse environmental and human health problems calling for safer alternative pest management options. Volatile organic compounds (VOCs) released by plants constitutively and in response to herbivory have been shown to enhance ecologically benign biocontrol alternatives to chemical insecticides for pest management.
