CD4 and follicular lymphoma: A small subset of findings displayed moderate heterogeneity (25% < I2 < 75%), and Significant heterogeneity was observed in a limited number of findings (mature T/NK‐cell lymphomas: CD3 on CD4, I2 = 75.7%; non‐follicular lymphoma: HLA DR on CD33dim HLA DR+ CD11b+, I2 = 75.7%, IgD on IgD+CD38br, I2 = 76%), thus indicating the robustness of our analytical findings.
