Consensus classification Description Definition
Consensus in (parent/caregiver-weighted vote) Consensus that the outcome should be included in the core outcome set 70% or more participants overall scoring as 7 to 9 AND < 15% participants scoring a 1 to 3 OR > 70% or more of parent group scoring as 7 to 9
Consensus out Consensus that the outcome should not be included in the COS 50% or fewer participants scoring as 7 to 9 in each stakeholder group
Neither consensus in nor consensus out (undetermined consensus) Uncertainty about the importance of the outcome so retain for next round Anything else
