Key sources of evidence in cancer research include:
- Randomized Controlled Trials (RCTs): These are considered the gold standard for clinical trials due to their ability to minimize bias. - Cohort Studies: These studies follow a group of patients over time to observe outcomes and potential risk factors. - Case-Control Studies: These studies compare patients with a particular outcome to those without, looking backward to identify risk factors. - Systematic Reviews and Meta-Analyses: These aggregate data from multiple studies to provide a high level of evidence on a particular topic.
