Calculating an epidemiological measure is rarely the difficulty. Interpreting it correctly is. This book explains what each measure means, when to use it, how to calculate it and how it is most often misread: prevalence, incidence, rates, risk and odds ratios, NNT, sensitivity and specificity, confidence intervals, confounding, outbreak indices and programme indicators. Worked examples, common errors and practice exercises in every chapter. 513-page eBook (PDF). eBook ISBN: 978-978-64098-4-9.
