Not all trials are about treating illness. Some help prevent disease or improve daily life. Here are the main types:

Treatment Trials

• Test new medications or therapies.
• Often for people with a specific illness.

Prevention Trials

• Try to stop disease before it happens.
• May involve vaccines, diet changes, or lifestyle habits.

Screening Trials

• Look for better ways to detect diseases early.
• Aim to find illness before symptoms appear.

Diagnostic Trials

• Test new ways to diagnose diseases.
• May help find faster or more accurate tests.

Quality-of-Life Trials

• Focus on improving daily comfort and well-being.
• May involve pain relief, mobility, or emotional support.
