After completion of milestone 7 “Development of data extraction form, protocol, and guidelines and adaptation of software”, we already had a technical face-to-face meeting on 4th and 5th of October in Utrecht. All researchers that extract data participated, namely FAD, IR-HSCSP, Nivel. UOI attended the meeting via Skype to provide input from the perspective of performing network meta-analysis. At this meeting, IR-HSCSP also led a risk of bias seminar. Another training session will be held on 3rd and 4th of December. Training sessions will be based on real-case RCT data extraction to ensure inter-researcher reliability.
