Although 12 individuals developed GC, one of them had LGD at baseline, and is not included in this table. The OLGIM system is not intended for staging individuals with LGD or HGD; however, as an observation of interest, the baseline OLGIM stage in this patient was II.
Gray cells denote numbers of individuals with the same OLGIM stage at baseline and 20 years of follow-up. On the left side of the diagonal are individuals who regressed; on the right, those who progressed.
