long-term studies

Long-term studies are research projects that observe and collect data over an extended period, often years or decades. They aim to identify patterns, causes, or effects that develop gradually, providing a comprehensive understanding of complex issues such as health, behavior, or environmental changes. By tracking the same subjects over time, these studies help researchers determine long-term outcomes and relationships that short-term research might miss. They are valuable for making informed decisions and developing evidence-based policies or treatments.
