π Understanding the Introduction Section in Scientific Writing
The introduction is a critical section of a scientific paper, setting the stage for the study by providing background, defining the research problem, and stating objectives. A well-structured introduction follows this format:
πΉ Background β Presents context, significance, and relevant literature.
πΉ Research Problem β Identifies gaps in existing knowledge.
πΉ Objective β Clearly states the purpose of the study.
π Example of a Background Section (Excerpt):
"Lung cancer is a leading cause of cancer-related mortality worldwide. Despite advancements in targeted therapies, overall survival remains low. The expression of PD-L1 has been proposed as a potential biomarker for predicting response to immunotherapy."
π Example of a Research Problem Statement (Excerpt):
"While PD-L1 expression has shown promise in stratifying patient response to immunotherapy, variability in outcomes suggests the need for further investigation into its predictive value across diverse patient populations."
π― Example of an Objective Statement (Excerpt):
"This study aims to evaluate the prognostic role of PD-L1 expression in lung cancer patients receiving immunotherapy and its association with survival outcomes."
