First, human CD4 cell counts are not distributed normally in the population; thus, a better measurement of treatment response is to examine the change in either CD4 cell percentage or the square root of the CD4 cell count.2 Because the CD4 cell count in selenium responders increased by only approximately 6.7%, it is unlikely that this reflects a biologically significant difference or that the CD4 cell percentage or the square root of CD4 cell counts changed significantly.
