What are the differences between real-world data and clinical trial data?

Real-world data (RWD) is collected from everyday health care settings, while clinical trial data (CTD) is gathered from controlled experiments.

Can you give examples of each type of data?

Sure! RWD includes electronic health records and insurance claims, while CTD comes from randomized controlled trials.

Why is real-world data important in healthcare?

RWD helps in understanding treatment effectiveness in diverse populations and can inform clinical guidelines.

Are there any limitations to using real-world data?

Yes, RWD can have issues like data quality, bias, and lack of standardization compared to the rigor of clinical trials.

How do researchers ensure the reliability of real-world data?

Researchers use various methods like data validation, statistical adjustments, and triangulation with other data sources to enhance reliability.
