aCD4 count and days from cryptosporidiosis diagnosis date.
bDifference in IgG response between a sample taken before and after date of cryptosporidiosis diagnosis.
cAverage of the two controls (CD4 count and sample date were matched to the respective cases).
M = missing data; IgG = immunoglobulin G; dx = diagnosis.
