The document discusses qualitative analysis and the process of interpreting qualitative data to answer a research question. It provides an example of a research question looking at whether IL-6 is increased in people with COPD. It then shares quotes from interviews with COPD patients describing how their symptoms impact their daily lives, such as having reduced mobility, function, and ability to participate in social activities. It outlines the procedure for qualitative analysis, including immersion in the data, coding, choosing codes inductively or based on existing theory, and interpreting themes that emerge from the codes.
