Based on the types of bias that are inherent in some study designs we can rank different study designs based on their validity. Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence * Level may be graded down on the basis of study quality, imprecision, indirectness (study PICO does not match questions PICO), because of inconsistency between studies, or because the absolute effect size is very small; Level may be graded up if there is a large or very large effect size.

In medical research, social science, and biology, a cross-sectional study (also known as a cross-sectional analysis, transverse study, prevalence study) is a type of observational study that analyzes data from a population, or a representative subset, at a specific point in time —that is, cross-sectional data . The studies may be interventional, may be observational, or may involve provider or patient self-reports or record reviews.

The current cross-sectional study aimed to under … The opposite of a cross-sectional study is a longitudinal study.While cross-sectional studies collect data from many subjects at a single point in time, longitudinal studies collect data repeatedly from the same subjects over time, often focusing on a smaller group of individuals that are connected by a common trait.
