Agreement in classifying the efficacy of albendazole between single Kato-Katz and duplicate Kato-Katz, Mini-FLOTAC, FECPAKG2 and qPCR.

The cross tables represent the agreement in classifying the efficacy of albendazole as ‘satisfactory’, ‘doubtful’ or ‘reduced’, between a single Kato-Katz (1x KK) and a duplicate Kato-Katz (2x KK), Mini-FLOTAC, FECPAKG2 and qPCR across the three study sites and for each soil-transmitted helminth species (9 observations). Drug efficacy is based on egg reduction rate (ERR) for microscopic methods and by means of reduction in genome equivalents (GERR) for qPCR. World Health Organization criteria to define drug efficacy into ‘satisfactory’, ‘doubtful’ and ‘reduced’ were previously recommended for a single Kato Katz (see Table 2).
