  • Data extraction is an important stage in
    systematic reviews because it captures critical
    study features in an organized and consistent
    format.
  • It is required for analyzing bias risk and
    synthesizing results. Interventional, diagnostic,
    and prognostic reviews take data from
    predetermined fields such as population,
    intervention, comparison, and results. Data
    extraction by hand can be time-consuming and
    repetitive, but intelligent software allows for
    automatic identification and medical data
    collection.
  • This semi-automation integrates with EBM and data
    science, and interest in its research is
    expanding alongside AI in other computer science
    domains.

INTRODUCTION
  • A data-extraction form based on crucial factors
    to prognosis to analyze the features of reviews
    and primary research was designed and is
    accessible on request from the first author.
  • Before the form was finished, it was pilot-tested
    by all review writers, and small changes were
    made following a discussion of the disparities in
    scores. One narrative review author rated all
    reviews, while others scored all reviews
    collectively.
  • Consensus sessions were convened within two weeks
    of the review's completion to resolve
    differences. A third reviewer was consulted to
    make the ultimate judgment if an agreement could
    not be achieved.

  • An item was rated 'yes' if positive information
    on that specific methodological item was
    discovered, for example, if it was obvious that
    sensitivity analyses were performed.
  • If it was evident that a certain methodological
    condition was not met, a 'no' was assigned for
    example, no sensitivity analyses were performed.
    'Unclear' was scored when there was a question or
    uncertainty.
  • A methodological item may be graded as 'not
    applicable' at times. The proportion and quantity
    of reviews within each answer category were
    given.

WHAT IS A DATA EXTRACTION TOOL IN RESEARCH?
  • A data extraction tool in research is a software
    or systematic approach designed to gather
    relevant information from various sources, such
    as research papers, databases, or surveys.
  • When conducting a systematic review of
    prospective cohort studies, it's crucial to
    extract relevant data from the included studies
    in a consistent and structured manner. Here are
    some variables to consider when creating a data
    extraction form for your systematic review
  • Study characteristics a) Study title b) Authors
    c) Publication year d) Journal e) Study location
    (country, region) f) Study design (e.g.,
    prospective cohort) g) Funding sources
  • Population characteristics a) Sample size b) Age
    range or mean age c) Sex distribution d)
    Ethnicity e) Baseline health status (e.g.,
    healthy, presence of specific conditions) f)
    Inclusion and exclusion criteria

  • Exposure or risk factor assessment a) Definition
    of exposure or risk factor b) Measurement method
    (e.g., questionnaire, biomarker) c) Exposure
    categories or levels d) Frequency or duration of
    exposure e) Confounding factors considered or
    adjusted for
  • Outcome assessment a) Definition of the
    outcome(s) of interest b) Measurement method
    (e.g., self-report, medical records, death
    certificates) c) Duration of follow-up d)
    Incidence or prevalence of the outcome(s) in
    exposed and non-exposed groups e) Loss to
    follow-up or attrition rate
  • Results a) Crude and adjusted effect estimates
    (e.g., hazard ratios, odds ratios, risk ratios)
    b) Confidence intervals or standard errors c)
    Statistical significance (e.g., p-values) d)
    Subgroup analyses or effect modification, if
    applicable
  • Quality assessment a) Newcastle-Ottawa Scale
    (NOS) score or another quality assessment tool b)
    Risk of bias assessment, if applicable

ABOUT PUBRICA
  • At Pubrica, we collect data from a wide range of
    sources and perform semantic annotation based on
    the research questions that you wanted to solve.
  • Pubrica has the vast majority of the data in
    doctor's notes electronic medical records,
    prescriptions, and similar information are
    available.
  • Although therein lies the golden possibility of
    big data in medical care, it's challenging to
    yield valuable insights due to complex,
    unstructured, longitudinal, and voluminous data.
