CROSS-SECTIONAL STUDIES IN HEALTH SCIENCES

We present practical examples of sample size and effect measures calculation for cross-sectional studies using online calculators and Epi Info software. Examples of studies using cross-sectional design from international peer-reviewed literature are also presented. This article provides general introduction to cross-sectional studies and does not substitute specialized literature in clinical epidemiology.
