HIVData: HIVData

Description Usage Details Author(s) References


A dataset of two sets of scores (particularly, correlation with protection against HIV and overlap with the Naive T-cell population) assigned to immunophenotypes measured by flow cytometry. 10 markers were measured: KI-67, CD28, CD45RO, CD8, CD4, CD57, CCR5, CD27, CCR7, and CD127.




This dataset consists of 2 numeric (LogRankPvals and OverlapScores) and 2 character (Pheno.Codes and marker.names).

Pheno.Codes vector is described in the RchyOptimyx function's manual.

LogRankPvals is a vector of log-rank test P-values to determine the correlation between HIV's progression and each of the measured immunophenotypes in 466 HIV positive patients (lower values represent a stronger correlation). For more details see the Aghaeepour manuscript below.

Ganesan et. al. define Naive T-cells as CD28+CD45RO-CD57-CCR5-CD27+ CCR7+ within the CD3+CD14- compartment. The OverlapScores vector has the proportion of Naive T-cells (as defined above) to the total number of cells in any given immunophenotype (a higher value represents a larger overlap).

marker.names is the name of all markers involved in the analysis.
