Chicago, IllinoisAges 18 years+ - NCT06911450Recruiting
Ultrasound test for lung strain in ICU patients
This study uses a special ultrasound technique to measure how the lungs stretch (pleural strain) during breathing. It aims to see if this measurement works in ICU patients, both those breathing on their own and those on a ventilator, and how it relates to the pressure needed to inflate the lungs.
Wuhu, AnhuiAges 18–75 - NCT06912100RecruitingEarly Phase 1
Probiotic & meal trial for better gut health

- How do I know if I qualify for a strains trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a strains trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
