Epidemiology and Statistics for the Ophthalmologist () Alfred Sommer

Description

This book provides ophthalmologists with a simple, clear presentation of epidemiologic and statistical techniques relevant to conducting, interpreting, and assimilating clinical research. The text is divided into two parts: the first covers epidemiologic concepts, various study types (e.g., prospective or longitudinal), and study organization (use of controls, randomness, sources of bias, choice of sample size); the second is devoted to the selection and use of relevant statistical manipulations, including determining sample size and testing statistical significance. It includes examples covering blindness registry data, incidence of visual field loss, sensitivity and specificity of tests for glaucoma, and sampling bias in studies of intraocular lenses.
