The article discusses how researchers use different methods to study health care issues. They talk about two main ways of doing research: qualitative and quantitative. Quantitative research focuses on numbers and facts, while qualitative research looks at people's thoughts and experiences. Qualitative research is becoming more popular in health care studies because it helps us understand people better. It can give us a deeper insight into how treatments work and how people feel about them. By using qualitative research, we can improve clinical trials and involve patients more in their care. This type of research helps us see the bigger picture and adds valuable information that numbers alone can't provide.
