What this Trial Is About
Researchers are studying whether switching from solid fuels to liquefied petroleum gas (LPG) and improving kitchen ventilation can reduce household air pollution and improve heart and lung health. This clinical trial aims to find out if using LPG, ventilation, or both together lowers pollution levels, improves cardiopulmonary function, reduces clinical events, and is cost-effective and sustainable. The study is randomized and includes multiple groups to compare these interventions.
