Basically it is not. However, there are studies being tiltled as prospective cross sectional study, but these kind fo terms should be used with caution and clear explanation.
Christian is Awesome maybe! <3 xx your welcome <3
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
If the diameter doubles (x2), the cross-sectional area quadruples (x4).
Other things being equal, more cross-sectional area will cause less resistance.
advantage of cross sectional study?
Yes, We can design a cross sectional study which its data collected in a retrospective format, so this study is called cross sectional retrospective study.

A longitudinal study is an alternative to a cross-sectional study. In a longitudinal study, data is collected from the same subjects over a period of time, allowing researchers to observe changes within individuals. This type of study provides a more in-depth understanding of how variables evolve over time compared to cross-sectional studies.
the cross-sectional study selects a sample that has all the age ranges the researchers are interested in verses one group that is followed throught time
Yes, cross-sectional studies can be classified as comparative or associative. Comparative cross-sectional studies involve comparing different groups at one point in time, while associative cross-sectional studies examine the relationship between variables within a single group at one point in time.

They can do.

A longitudinal study and a cross-sectional study are methods of collecting scientific data. A longitudinal study is the method that gathers data on a subject for a particular period of time and the subject's response to particular variables. A cross-sectional study is where more than one subject is used for the collection of data at different points in time in response to particular variables. These types of studies are sometimes used to determine correlation.
