A good research workWhat are the key factors for a good research project?– High quality research work (manuscript)
• topic/issue• question• “Literature Review”• methodology• results• discussion section• conclusion
![Page 8: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/8.jpg)
Structure of a Research Report
• A research report/original article consists of the following sections:
– Title References■– Abstract ■ Appendixes– Introduction ■ Author Note– Method ■ Footnotes– Results ■ Tables (if any)– Discussion Figures (if any)■
![Page 9: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/9.jpg)
![Page 10: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/10.jpg)
General Guidelines
Write clearly.Use economy of expression (i.e., be
concise).Be precise.Follow grammatical rules.Write fairly.Don’t use abbreviations except you have
explained earlier (KSA, KSU……).
![Page 11: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/11.jpg)
General Guidelines
Write an interesting report.– Present ideas and findings directly.– Interesting and compelling manner – Reflects your involvement with the research
problem.– Strive to tell a good story about your research.
![Page 12: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/12.jpg)
Results
![Page 13: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/13.jpg)
Results– The climax of the report – The actual findings of the study.– Answer the questions & fulfill
hypothesis/objectives – BUT “stick to the facts” – Negative findings??– NO interpretation of the findings.
![Page 14: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/14.jpg)
Components of Results section• Results should answer main hypothesis or
research question(s).
• Order of presenting results is arbitrary.
• Results that are "sidelights" should not receive equal weight.
![Page 15: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/15.jpg)
• When presenting the results for the main hypotheses, consider:
– Clear, concise, simple– Enough detail is presented to allow the reader
to determine whether the effect of the study (vs. chance alone, not bias or sloppy technique) produced the significant statistical value?
– Adverse effects are reported?
![Page 16: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/16.jpg)
• Do not state any differences were present between groups unless a significant P value is attached.
• Don’t comment on results.
• Don’t attach the entire statistical output.• • Select those descriptive and inferential statistics
you wish to use, and place them in the order that seems reasonable.
![Page 17: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/17.jpg)
– The structure of a typical paragraph in the Results section is as follows:1. Start with simple and descriptive statistic.
2. Present a summary of this descriptive statistic in the text itself, in a table, or in a figure.
3. Move to more analytic findings
![Page 18: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/18.jpg)
4. Tables/figure : point out the major findings on which the reader should focus.
5. Present the reasons for, and the results of confidence intervals, effect sizes, and inferential statistics.
6. State the conclusion that follows from each test.
7. DO NOT discuss implications.
![Page 19: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/19.jpg)
8. Tables and graphs must stand alone (Can a member of your department unfamiliar with the study pick up your graph and explain its meaning to you?).
9. Text should highlight the importance or meaning of the figures and tables, not repeat the data contained within them.
10. Tables and graphs both carry a necessary part
of the message- use both
![Page 20: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/20.jpg)
11. Present absolute numbers and
percentages so reviewers can judge the
significance of the findings.
12. Statistical significance; P-value/95%
CI….
![Page 21: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/21.jpg)
Why is Table 1 in most studies?
• Describe the characteristics of the study population.
• Shows that demographic and prognostic variables were evenly balanced in the process of random allocation of subjects to experimental and control groups.
![Page 22: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/22.jpg)

Tables and Figures
–Tables and/or figures are attached at the end of the research manuscript.
–Only one table or figure on a page.–Each table/figure are explained well
with the titles.

Discussion• A clear and concise statement of the essential findings.
• A clear presentation of how the findings support or refute the hypotheses.
• A description of how the results are similar to or different from previous research.
• Limitations or problems in the research.
• Specific ideas for additional research based on the findings.
![Page 29: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/29.jpg)
Discussion
Interpret your resultsSometimes combined with results into one sectionMay repeat specific to general writing multiple times (e.g. for each objective or key finding)
![Page 30: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/30.jpg)
• Don’t repeat results Order simple to complex (building to conclusion
• Explain how the results answer the question under study Emphasize what is new, different, or important about your results.
• Consider alternative explanations for the results
![Page 31: BY DR. HAMZA ABDULGHANI MBBS,DPHC,ABFM,FRCGP (UK), Diploma MedED(UK) Associate Professor](https://reader036.fdocuments.us/reader036/viewer/2022081503/568163bf550346895dd4e037/html5/thumbnails/31.jpg)
• Avoid biased language or biased citation of previous work.
• Don’t confuse non-significance (large P) with "no difference" especially with small sample sizes.
• Don’t confuse statistical significance with clinical importance .
• Never give incidental observations the weight you attach to conclusions based on hypotheses generated before the study began
