HMMR and atrial fibrillation: When exclusively analyzing intrafollicular RHAMM expression, OS, PFS, and TFS were all significantly shorter among patients with high marker levels (cutoff AF = 0.0096, p = 0.032; cutoff AF = 0.0206, p = 0.028; and cutoff AF = 0.0096, p < 0.001, respectively), Figure 2C–E.
