What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.

Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks back at the medical records of over 100,000 hospitalized patients to identify which health conditions and factors are linked to a higher risk of death in people with venous thromboembolism (VTE) — blood clots in the veins, including deep vein thrombosis and pulmonary embolism. Researchers will compare patients who survived with those who died to spot high-risk factors such as respiratory failure, sepsis, and hemorrhage. The goal is to better understand what makes some VTE patients more vulnerable, which could help guide future care.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could help doctors identify which VTE patients are at highest risk of dying, potentially leading to more targeted monitoring and treatment.
What could go wrong
Because this is a retrospective observational study, it can only show associations, not cause and effect. The findings may not apply to other hospitals or patient groups.
