Basic Statistics and Epidemiology is a straightforward primer in basic statistics that emphasizes its practical use in epidemiology and public health, providing an understanding of essential topics such as study design, data analysis and statistical methods used in the execution of medical research.
Assuming no prior knowledge, the clarity of the text and care of presentation ensure those new to, or challenged by, these topics are given a thorough introduction without being overwhelmed by unnecessary detail. An understanding and appreciation of statistics is central to ensuring that professional practice is based on the best available evidence, in order to treat and help most appropriately the wider community.
When aetiology is unknown Less time and money Rare diseases and diseases with long latent periods Dynamic population. Disadvantages Difficult to establish temporal sequence Rare exposures Greater chance of bias.
Cohort studies Prospective Exposed and Unexposed populations followed into future for the development of outcome. Retrospective Exposure and outcome have already occurred Basic study design is always from exposure to disease. Rare exposures Direct estimation of risk Less chance of Bias Prospective Multiple effects of a single disease Well defined temporal sequence.
Intervention studies Investigator assigns exposure to the participants Study design is from exposure to outcome Ethical problems for hazardous exposures Studied by attempts to eliminate the exposures. Intervention studies Advantages Most reliable evidence in epidemiological research because the exposure is randomly assigned Randomisation controls the effects of the risk factors not considered at the time of the study.
