Since there seems to be no uniform procedure for when and how the IRR is assessed in systematic reviews, we would be interested to know how you proceeded with regard to compiling the study sample and the rating steps in a systematic review:

- IRR with regard to the inclusion criteria (in title/abstract and full text screening), the coding items and/or the quality assessment criteria;

- how did you compile the study sample for determining IRR and with what number od studies?

- with which percentage threshold?

Thank you in advance!
