I am trying to write a systematic review on factors that affect human's discrimination ability of mixed odors. The data obtained from these types of studies will contain categorical data as observations like yes/no. Can I conduct a meta-analysis for such type of data?
You can look for meta-analysis of dichotomous variable (presence or absence of a specific trait or factor).
Odds ratios and risk ratios are commonly used as effect sizes when working with dichotomous variables. All meta-analysis software that I am familiar with is set up for using odds ratios and risk ratios as effect sizes.
Yes! But, it must always follow the guidelines for doing systematic reviews. So, look for the guidelines and study them to understand what you need to include or exclude. Or, to understand how you should handle such a study. Thank you!
