Research articles
Title & Author(s): The title should be descriptive of the research, and generally the individual responsible for the majority of the research is the primary or first author.
Abstract: The abstract should accurately represent the content of the article; for more information see Structured abstracts.

Research articles ComponentsIntroduction:
The introduction lays the foundation for the paper by stating the research problem, the rationale for the study, the research question, and the hypothesis. Some journals call this section the “background”, which usually contains a literature review.
![Page 7: By Dr.Eslamipour. We learned: What is EBD? Why EBD? Evidence-based practice process](https://reader030.vdocuments.site/reader030/viewer/2022032604/56649e5f5503460f94b58ddd/html5/thumbnails/7.jpg)
Methods:
The method’s section details how the study was done, including:
Participants: demographic information of sample, sampling method, relevant characteristics, informed consent, and institutional approval
Equipment (if applicable): for example, diagnostic tools
Research Design: research methodology, protocol, and timeline for interventions and measurements
Data Analysis: describes data collection methods and procedures for statistical analysis
![Page 8: By Dr.Eslamipour. We learned: What is EBD? Why EBD? Evidence-based practice process](https://reader030.vdocuments.site/reader030/viewer/2022032604/56649e5f5503460f94b58ddd/html5/thumbnails/8.jpg)
Research articles componentsResults:
The results section should simply state the findings, without bias or interpretation.
Research results can only confirm or reject a hypothesis.

Discussion:
This section describes the major findings of the research, including whether the results are statistically significant.
This section compares the results to the current literature on the same or similar topics, and describes how these results can be generalized to other situations.
Authors should discuss any limitations of the study and cite unanswered questions
