  2. What are Research Papers For? » Build body of knowledge

    » Help formulate research questions and experiment designs From: reddit.com/r/ProgrammerHumor
  3. Peer-Review » Allows experts in a field to self- regulate

    publication standards and assure validity, quality and originality of journal articles » Publications in peer-reviewed journals have more value From: opg.optica.org/reviewer
  4. Large Volume of Publications » Publications are growing exponentially “To

    be updated with current knowledge, a physician practicing general medicine has to read 17 articles a day, 365 days a year.” (RV Subramanyam, 2013) Date Range # Publications in Medline 1978-1985 272,344 1986-1993 344,303 1994-2001 398,778
  5. Journal article publications have increased since the publication of this

    paper » Publication output in science and engineering hit 2.9 million articles in 2020 Source(s): National Center for Science and Engineering Statistics; Science-Metrix; Elsevier, Scopus abstract and citation database, accessed May 2021; World Bank Country and Lending Groups, accessed March 2021.
  6. “We are drowning in information but starved for knowledge.” —

    John Naisbitt - Publications are growing exponentially. - “To be updated with current knowledge, a physician practicing general medicine has to read 17 articles a day, 365 days a year.” - Logical methodology for a parsimonious approach. Date Range # Publications in Medline 1978-1985 272,344 1986-1993 344,303 1994-2001 398,778 (RV Subramanyam, 2013)

  18. Methodology: Step 2 Read the title. » Is the paper

    a review article or original research?
  19. Methodology: Step 3 Read the abstract. » What are the

    background or hypothesis, general methods, results and conclusions? (International Helminth Genomes Consortium, 2019)
  20. Methodology: Step 4 Read the conclusion. » What claim does

    the research assert? » Were the conclusions logically based on reported data? » Will the results assist in clinical practice or further research? (Rosa et. Al 2018)
  21. Methodology: Step 6 Read the intro. » Why was this

    study performed? » What was the research hypothesis? » What were the aims and objectives of the study? (Woldayay et al., 2021)
  22. Methodology: Step 7 Read the methods. » What procedures were

    followed? » Is there any supporting information? » Inclusion/exclusion criteria? (Abbasi et al., 2018)
  23. Methodology: Step 7 Read the methods. » How was statistical

    significance determined? – P-value cutoffs – Tests implemented – Software used (Immediato et al., 2016)
  24. Statistics are Crucial! From: miro.medium.com » Descriptive Statistics – Mean,

    median, range, standard deviation – Frequency – Sensitivity and specificity
  25. Statistics are Crucial! From: biochemia-medica.com » Inferential Statistics (Hypothesis testing)

    – Drawing conclusions or making predictions about a population based on data observed in a sample – Significance testing
  26. Statistics are Crucial! From: scyther5/iStock/GettyImages » Parametric tests: – Normal

    curve test (Z test) – Student’s t-test – Analysis of variance – Pearson correlation coefficient – Linear regression
  27. Statistics are Crucial! » Non-parametric tests for quantitative data: –

    Wilcoxon signed rank test – Mann Whitney rank sum ‐ test – Kruskal Wallis test ‐ From: scyther5/iStock/GettyImages
  28. Statistics are Crucial! » Non-parametric tests for qualitative data: –

    Chi square test ‐ – McNemar test – Fisher’s exact test From: scyther5/iStock/GettyImages
  29. Methodology: Step 8 » What were the key findings regarding

    the hypothesis? » Is data reported in graphs or tables? » Which aspects were significant/non-significant? Read the results. (Woldayay et al., 2021)
  30. Methodology: Step 9 » How were research questions answered? »

    What was the interpretation of data analysis? » Were there limitations to the study? Read the discussion. (Torgerson et al., 2015)
  31. Methodology: Step 10 » Was your initial assessment of the

    journal article correct? – Research claim – Supported by data – Practical application or future research Re-read the conclusion. (Simonato et al., 2020)
  32. Methodology: Step 11 » Were references formatted correctly? » Were

    all the references cited in the text? » How old are references? Read through references. (Kreiman and Maunsell, 2011)
