Introduction
Why did you start?
Readers’ expectations• Sufficient background information• Understand and evaluate the results • Without referring to previous publications
Concise, adequate Not a review
Introduction
• Review pertinent literature• Define lacunae in current knowledge• Provide rationale for your study
– What gap in knowledge did you try to fill?– What controversy did you try to resolve?
• State the aim of the study
Introduction
• Brief, clear, to the point• Written in present tense
• May state the study group, study design and methods used
Introduction
• Key references: to support background information
• Refer to – your previous preliminary work– your own closely related papers
• Define any specialized terms, definitions or abbreviations you intend to use
Example
We wish to suggest a structure for the salt of deoxyribose nucleic acid (D.N.A.). This structure has novel features which are of considerable biological importance.
Watson JD, Crick FHC. A structure for deoxyribose nucleic acid. Nature 1953; 171: 737-8.
Methods
What did you do?
Methods
• What all was done?• How was it done?• When was it done?• Who did it ?• How were the results analyzed?• Did you have ethical clearance to do so?
Methods
– Present methods in chronological order– Subheadings should match those in results
‘internal consistency’
– In past tense– Be precise
Methods: checklist• Does it describe
– What questions was being asked?– What was being tested?– How reliable was the measurement?
• Were the parameters recorded and analyzed correctly?
• Would a reader be able to repeat the same experiment?
Results
Answers
What did you find?
Results: Before writing
• Collate data
• Prepare master tables– Re-check accuracy
• Analyse– List all the findings– Identify the important ones
Results: The components
• Text Story
• Tables Meat
• Figures Drama
Results
• Results of all experiments in natural orderin subsections similar to methods
• Do not duplicate informationtext, tables, figures
• Statistical analysis
Results
• Should not include– Any methods– Data for which methods are not included– Interpretation of data – References
Results: Tables

BODY
Results: Table or figure
• Prefer tables
• Use figures only for illustrative
• Bar, histogram, pie: ? table
Difference in written and oral communication
Results: Text or Tables
• Number of items
• Few variables: Text
• Many variables: Table
Figure: in place of text
