Controrchis spp. total egg counts. Comparison between calibration variables: methods, FSs, preservation methods and dilutions. a Total number of EPG using the FLOTAC technique with groups FS1-FS6. b Total number of EPG using the Mini-FLOTAC technique with groups FS1-FS6. c Total number of EPG using the FLOTAC technique with FS7. d Total number of EPG using the Mini-FLOTAC technique with FS7. Letters above the bars indicate the homogeneous groups based on the contrasts done. Differences for bars with the same letter were not statistically significant while those with different letters were statistically different. In all the bars the standard error is represented as a measure of dispersion around the mean
