Clinical Trials

Clinical research is human-centred medical research. Observational studies and clinical trials are the two types.

Observational studies look at people in their natural surroundings. Researchers collect data, categorize volunteers into groups based on broad characteristics, then assess changes over time. For example, researchers may collect data on a group of older persons over time through medical check-ups, tests, or questionnaires to learn more about the effects of various lifestyles on cognitive health. This research may aid in the discovery of novel clinical trial options.

Clinical trials are human research studies that are used to assess the effectiveness of a medicinal, surgical, or behavioural intervention. They are the most common technique for researchers to determine whether a novel treatment, such as a new medicine, diet, or medical equipment (such as a pacemaker), is safe and effective in humans. A clinical trial is frequently performed to determine whether a new treatment is more successful than the current treatment and/or has fewer negative side effects.
