The method used should be clearly described and concisely expressed, including the selection of observation and experimental subjects, apparatus and procedures used, which should also be stated in sufficient detail to allow the experiment to be replicated. However, the confidentiality of patients and subjects should be protected and ensured by not mentioning their names, hospital numbers and even in the materials being used for illustration. In animal experiments however, all appropriate procedures must have been complied with as directed by the National Research Council or care of the use of laboratory animals. The statistical test utilized should also be mentioned. Products used in experiments should be properly identified by their manufacturer’s name(s) as appropriate.
Results: should be presented in a logical sequence in the text, tables, and illustrations, giving the main or most important findings first. Avoid the repetition in the text and all the data in the tables or illustrations and only important observations should be emphasized or summarized, which should be clearly stated for understanding. No vertical lines are permitted on the tables and there should be no duplication between the tables and the results.
Discussion: Repetition of results should be avoided. Rather, there should be analytical discussion of the implications of the results and other observations as related to the study. It may be worthwhile to compare your results with the previous works done in this area by previous investigators. It is advisable to use current literatures on the subject mainly and quoting data from previous works repeatedly will not be permitted. Plagiarism is frowned at and will not be tolerated in the journal. New finding(s) can be discussed as well as it contributes to knowledge.
