Who could benefit from this research
✓Could help
Ideal participants are the over 71,000 individuals already enrolled in the World Trade Center Health Registry who were 9/11 responders or survivors.
✕Less likely to help
Patients not directly connected to the 9/11 events or not enrolled in the Registry would not directly benefit from this specific effort.
What this research studies
The World Trade Center Health Registry is the largest and longest-running effort to track the long-term health effects of the 9/11 disaster. We connect with people who were involved in rescue and recovery work, or who were in lower Manhattan on 9/11, to understand how their health has changed over time. This work helps us learn about physical and mental health conditions that may emerge years later. Our goal is to provide valuable information that can improve care and policies for 9/11 survivors and responders.
Why it matters
Potential benefit: This work helps identify and understand long-term health conditions related to 9/11, which can lead to better care and support for affected individuals.
How similar studies have gone: The Registry has a strong track record, with 142 peer-reviewed publications already contributing significantly to the understanding of 9/11 health outcomes.
