Principal component analysis of mRNA probes in the Botswana cohort. Principal component analysis using the 26 643 informative mRNA probes [i.e. genes with good detection in all samples (i.e. detection P < 0.05 in all samples), >1.2-fold change between any two samples and background level of expression about 82]. Data are shown for each patient from group R (i.e. women with post-LEEP disease recurrence/relapse, indicated with black circles) and group NR (i.e. women without post-LEEP disease recurrence/relapse, indicated with white squares) of the Botswana cohort.
