Hello!

We have conducted a survey with anonymized responses. But we do want to know which participants have fully completed the survey in order to give them co-authorship. In the list of participants we can see green checkmarks of participants who have completed the survey. Unfortunately, the number of green checkmarks does not match the number of participants we get data from. So when we download the data, we get the responses from 63 participants but in the list of participants there are only 60 participants with a green checkmark. Therefore, we do not know from 3 participants that they also fully completed the survey.

Can anybody help us with this? We would really appreciate your help!
