Summary

This completed study looked at 300 patients with pleural effusion—fluid buildup around the lungs—to find out what caused it. Researchers reviewed medical records to classify the fluid type and identify underlying conditions like heart failure, infection, or cancer. The goal was to improve how doctors diagnose and manage this common problem.
