Transarterial embolisation plus percutaneous alcohol injection vs percutaneous alcohol injection

Mortality at maximal · people with early‐ or very early‐stage hepatocellular carcinoma ineligible for surgery

It is very uncertain whether transarterial embolisation plus percutaneous alcohol injection changes mortality at maximal compared with percutaneous alcohol injection (very low certainty).
