The correlation between T_N cell percentage and long-term survival. a, b Comparison of CD8⁺ T_N cells (a) or CD4⁺ T_N cell (b) percentage in peripheral blood at different time points after CAR T cell infusion between long-term response and relapsed patients (T_N, naïve T cells). CD8⁺ or CD4⁺ T_N cells percentage were ranked and divided into four quartiles, from lowest (Q1) to highest (Q4). c, d Relapse-free survival (c) or overall survival (d) difference between patients with low CD8⁺ T_N cells percentage (Q1) and those with high CD8⁺ T_N cells percentage (Q2–4). e, f Relapse-free survival (e) or overall survival (f) difference between patients with low CD4⁺ T_N cells percentage (Q1) and high CD4⁺ T_N cells percentage (Q2–4)
