  1. aConsensus read was determined by consensus of the primary reviewers with a third senior reviewer in cases where there was disagremment between the reviewers A and B for the FE-CMRV
  2. bUltimate assessment was determined by the senior reviewer (J.P.F.) for cases with disagreement between the consensus FE-CMRV and reference standard
