Clinical and immunological characteristics of viremic non-progressors and putative progressors.

(A) Estimated duration of HIV diagnosis based on first HIV+ test. (B) Plasma HIV RNA in VNPs and PPs as measured by RT-PCR. (C) The fraction of CD4+ T cells in VNPs and PPs measured by flow cytometry. (D) Absolute CD4+ T cell count in blood from VNPs and PPs based on CD4+ T cell fraction and lymphocyte count by CBC. p values from Mann Whitney T test. Line reflects median. Circles, VNPs; Squares, PPs.(A) 基于首次HIV阳性检测结果估算的HIV诊断时长。 (B) 经逆转录聚合酶链式反应（RT-PCR）检测的VNPs与PPs的血浆HIV RNA水平。 (C) 经流式细胞术检测的VNPs与PPs中CD4+ T细胞占比。 (D) 结合血常规（CBC）检测的淋巴细胞计数与CD4+ T细胞占比，计算得到的VNPs与PPs外周血CD4+ T细胞绝对计数。 所有p值均来自曼-惠特尼U检验；图中线条代表中位数，圆圈代表VNPs，方块代表PPs。
