2 different core sets or just one? - Calcium Pyrophosphate Deposition (CPPD) Core Domain Set Endorsement https://omeract.org/forum/cppd-cds/2-different-core-sets-or-just-one/ This forum provides a dedicated space for open discussion as OMERACT Working Groups move through the Core Domain Set Endorsement and Instrument Selection Ratification processes. Each Working Group has its own forum where participants can ask questions, seek clarification, and share constructive feedback. These discussions foster transparency, inclusivity, and collaboration, helping ensure all voices are heard and that participants feel confident in their understanding before completing an endorsement or ratification. en-CA Fri, 17 Apr 2026 05:03:14 +0000 wpForo 60 Answer to: 2 different core sets or just one? https://omeract.org/forum/cppd-cds/2-different-core-sets-or-just-one/#post-18 Tue, 28 Oct 2025 13:00:55 +0000 Thanks for this comment. The decision to develop two core sets was made very early in the development process, with a vote to take this approach at a virtual OMERACT SIG in 2020. We used this approach in all the Delphi exercises. This aligns with the approach taken for the OMERACT core domains for gout, another crystal arthritis (gout flare domains and long-term gout domains). For CPPD, the core outcomes for acute CPP crystal arthritis and the core outcomes for chronic and recurrent CPPD disease are not the same, although there are some overlapping domains (for example pain intensity, overall function, and patient global assessment).

But having arrived at this point, I note the core sets show strong overlap, so in a revision you could merge them and make the differences situation-specific.
