General health (n=903): fair/poor vs. excellent/very good/good, chi-square tests were used to compare those meeting, to those not meeting, each definition of MJOA for rOA and sxOA
2
Patient Reported Outcomes Measurement Information System (PROMIS) Physical Function (n=893): higher scores indicate better function (range 10–50), t-tests were used to compare those meeting, to those not meeting, each definition of MJOA for rOA and sxOA
