What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Positively Smoke Free - Mobile (smartphone app) and low-dose CT scan
What this could lead to
If successful, this could show that combining a tailored smoking cessation app with lung cancer screening helps people with HIV quit smoking, potentially reducing their risk of lung cancer.
What could go wrong
This is a small feasibility study (100 participants) with no control group, so results may not be generalizable. Adherence to the app may be low, and quitting smoking is difficult even with support.
