    DEMONSTRATIONS

    There are a total of 271 presentations/activities available over all 15 Lessons (i.e, chapters) of ActivEpi.  The icons provided below represent a small sample ( 18 ) of these presentations  from several, but not all, Lessons of the ActivEpi CD-ROM.

    Instruction

    To view any presentation, you need to click on one of the two icons provided in the table for the presentation: if you are using a Windows computer with media players such as Windows Media Player or Real Player, you should click on the icon in the left column, whereas if your computer is an Apple MacIntosh with Quicktime or Real Player, you should click on the icon in the right column. If you do not have any of above software on your computer, you may have to install the appropriate software. 

    Here are the links to download appropriate media player:

    Note: Some Windows computers may be able to open ".mov" files in the right column and some Macintosh computers may be able to open ".wmv" files in the left column, depending on what media player software is installed on the computer.

    Dr Kleinbaum (CDC/EIS) comedy skit

  • Downloading time will vary depending on the high speed internet access (cable, DSL) due to the nature of large movie file size, so you may have to wait several seconds before the activity you've selected begins to run. Users who access internet with analog phone line may not be able to download them.

    Please note that these demonstrations are recordings that use Movie Player files, so they have no interactive features for the user. In contrast, the actual content on the ActivEpi Web and CD-ROM is not delivered as a recording and consequently, allows user interaction.  Note also that the video and audio quality on the demonstrations provided here is not nearly as good as on the ActivEpi Web or CD-ROM versions.

    Introduction to Epidemiology

    Examples: Aspirin and heart disease; Smoking and lung cancer; Powerlines and child leukemia; Age and breast cancer screening

    Compare the characteristics of risk and rate.

    Define, illustrate and interpret a risk ratio.

    Example: Quit smoking and CHD survival

    Describe how bias can occur when subjects are misclassified by exposure or disease.
    State the purpose of diagnostic test studies and how they are related to misclassification of disease.
    Define and interpret predictive value. Explain the related concept of post-test probability.

    Define and illustrate the concept of confounding.

    Example: Chemical exposure and lung cancer

    Identify the difference between the confounding and interaction.

    Example: Alcohol consumption and bladder cancer

    Describe what is involved when undertaking a simple analysis.

    Examples: Quit smoking and CHD survival; Diarrhea outbreak at resort; Borderline cholesterol and mortality

    Describe and illustrate two options for control at the analysis stage.

    Example: Personality type and CHD risk

    Illustrate a stratified analysis when single dichotomous variable is controlled.

    Example: Chemical exposure and lung cancer

    Describe the initial steps in a stratified analysis involving several control variables.

    Describe and illustrate the purpose and characteristics of Mantel Haenszel Test.

    Example: Chemical exposure and lung cancer

    Define and illustrate what is matching.

    Example: Aspirin and Reye’s Syndrome

    General Principles for analyzing matched data.

    Describe 4 types of strata resulting from pair matching.

    Example: Estrogen use and endometrial cancer

    Quizzes

    To view any quiz, you need to click on one of the two icons provided for the quiz: if you are using a Windows computer with media players such as Windows Media Player or Real Player, you should click on the icon in the left column, whereas if your computer is an Apple MacIntosh with Quicktime or Real Player, you should click on the icon in the right column. If you do not have any of above software on your computer, you may have to install the appropriate software. 

    Note: The quizzes are demonstrated as recordings that use Movie Player files, so
    they have no interactive features for the user. In contrast, the actual content
    of quizzes on the ActivEpi CD-ROM requires user interaction, including feedback
    to the user after an answer is selected, and the opportunity to try another
    answer if a wrong answer is selected.
