TABLE 3.

Cartilage Integrity Scores for the Yucatan Cohort Assigned Using PCD-CT Images

Sex Index, Male/Female-Number	Control Knee	MIA Knee
F-1	Grade 0	Grade 1
F-2		Grade 1
F-3		Grade 3
F-4		^*Grade 1/grade 2
M-1	Grade 0	Grade 3
M-2		Grade 3
M-3		Grade 3
M-4		Grade 3

Cartilage heterogeneity observed with potential thinning <50%. Exact test of omnibus symmetry between MIA and control knee scores was applied, P = 0.004, statistically significant.

PCD-CT indicates photon-counting detector computed tomography; MIA, monoiodoacetate.
