“…In summary, only 8.6% (9 studies) of the studies covered all mandatory domains as recommended by OMERACT [ 26 , 31 , 41 , 42 , 75 , 76 , 87 , 112 , 130 ] and only 6.7% (7 studies) covered all mandatory and optional domains [ 26 , 31 , 41 , 42 , 76 , 112 , 130 ]. Remarkably, although the OMERACT recommendations have been available since 2009 [ 5 ], only eight studies referred to those recommendations in the methods section or in the discussion [ 30 , 56 , 73 , 79 , 80 , 113 , 125 , 126 ]. Seven studies cited the OMERACT core set because they explicitly conformed to their recommendations [ 30 , 56 , 73 , 80 , 113 , 125 , 126 ].…”
