a
As egg morphology does not allow species-level identification of hookworms, this row combines the results for both A. duodenale and N. americanus PCRs. The rows below consider only samples with positive culture, which allowed species-level identification.
b
One sample was both “Microscopy +/GIPH −” for A. lumbricoides and “Microscopy −/GIPH +” for S. stercoralis, and was therefore counted in each column but considered as a single sample for the calculations.
