It’s number of studies: for example

5/10 studies at low risk of bias = 50% green

2/10 studies at medium risk of bias = 20% yellow

3/10 studies at high risk of bias = 30% red

Total = 100% (10 out of 10 studies)

How do you calculate percent? Does it based on the number of people in the study？

]]>Hi, these are just calculated by hand (e.g., 5/10 are low risk of bias = 50%). So the categories add up to 100%.

Hi, depending on the reference style I guess you could just use the reference for the website:

(Example in APA)

Kok, R. N. (2017). High-resolution Risk of Bias assessment graph [Computer software]. Retrieved from https://www.robinkok.eu/2016/03/11/risk-of-bias-assessment-graph-in-excel/

And refer to that in-line with version number 2.6 🙂
