Classification based on the percentage of CADM1⁺ cells among the CD4⁺ cells according to a CADM1 versus CD7 plot. The CADM1 versus CD7 plot in CD4⁺ cells and clinical data of two representative cases are shown. The P (CADM1⁻CD7⁺), D (CADM1⁺CD7^dim), and N (CADM1⁺CD7⁻) subpopulations were gated as described in our previous report. Cases were classified based on the percentage of CADM1⁺ (D + N) cells as follows: G1, D + N ≤ 10%; G2, 10% < D + N ≤ 25%; G3, 25% < D + N ≤ 50%; and G4, 50% < D + N. A, Case 1. D + N = 22.9%, which was classified as G2. B, Case 2. D + N = 58.1%, which was classified as G4. Ably, abnormal lymphocytes; AC, asymptomatic carrier; ATL, adult T‐cell leukemia/lymphoma; CADM1, cell adhesion molecule 1; PBMC, peripheral blood mononuclear cells; PVL, proviral load; sIL‐2R, soluble interleukin‐2 receptor
