Detection and genotyping of Cryptosporidium species in diarrheic patients in Assiut, Egypt: A parasite of potential zoonotic transmission

Different study designs are applied in research fields, and sufficient knowledge of study types may help design the research methodology.Type of study is referred to as one of various methods for obtaining data information collected by researchers depending on their goals, and the questions they're trying to answer.This simply means that several study types can answer the study question, but which is the most appropriate?There are two main categories of studies; observational and experimental.Observational studies involve collecting, and analyzing data without researcher' intervention (i.e., the experimental execution of a certain plan); while experimental studies require researcher intervention.When researchers want to answer a specific question related to a certain topic, they may choose an observational approach, or experimental design.The present editorial aims to clarify the important differences between study types to select the best one answering the study question, or confirming/denying the study hypothesis. How to write a research question?During clinical practice and/or reading literature, the researcher finds a problem that is worth solving.One of the most essential steps in problem solving is developing a study question/hypothesis.It directs the investigation, provides a clear focused goal, and addresses a problem or issue that researchers attempt to answer.In 2007, Brian Hulley created the FINER model that stands for the characteristics of a study question [1] .The FINER criteria aren't just a checklist, i.e., they are essential elements ensuring a strong impact and meaningful study.The criteria included 1) feasibility where the question is within the researchers' abilities, and resources, 2) interesting to reviewers, and other colleagues to conduct similar researches, 3) novel providing new insights and may help confirm existing research, 4) ethical where the study participants provide their informed consent, are informed with the study results, and receive the appropriate management, 5) relevant where the researchers choose topics related to their society's health problems.
