| Summary: | Defining the limits of normality -- properties of clinical measurements -- distributions -- reference ranges and the criteria for abnormality. Evaluation of diagnostic tests: Interpretation of tests -- statistical significance. Use of diagnostic tests: the testing band -- calculation of the probability of disease -- differential lists -- screening for disease. Measuring the commonness of disease: expressing the frequency of clinical events -- factors affecting the interpretation of incidence and prevalence. Risk assessment and prevention: risk factors -- uses of risk -- cohort (prospective) studies of risk -- case control (retrospective) studies of risk -- prevalence surveys of risk -- biological plausibility and cross sectional study designs. Measuring and communicating prognosis: natural history versus clinical course -- prognosis as a rate -- survival analysis. Design and evaluation of clinical trials: efficacy effectiveness and compliance -- case studies -- clinical trials in practice. Statistical significance: interpretation of statistical analyses -- selection of an appropriate statistical test -- parametric and nonparametric tests -- using a tree diagram to select a statistical test -- sample size. Medical ecology and outbreak investigation. Measuring and expressing occurrence: case definition -- reporting -- case studies. Establishing cause: multiple causation -- Koch's postulates -- case study. Source and transmission of disease agents: modes of transmission -- factors affecting communicability. Cost of disease: defining disease in economic terms -- decision analysis -- strategies to reduce the frequency of disease -- case studies. |
