Summary of genotyping accuracy among sample groups stratified by multiplexing level.

aMean genotype concordance rates was not significantly different (P = 0.491, Kruskal-Wallis test) across multiplexing levels. In addition, there was no significant correlation between mean genotype concordance rates and multiplexing levels (coefficient = -0.025, P = 0.746).bMean genotype concordance rates was marginally different (P = 0.050, Kruskal-Wallis test) across multiplexing levels. In addition, there was significant correlation between mean genotype concordance rates and multiplexing levels (coefficient = 0.155, P = 0.041).cMean genotype concordance rates was not significantly different (P = 0.184, Kruskal-Wallis test) across multiplexing levels. In addition, there was no significant correlation between mean genotype concordance rates and multiplexing levels (coefficient = -0.008, P = 0.917).dP values for comparison of mean genotype concordance rates by Friedman test.eP values for matched pairwise comparison of mean genotype concordance rates by Wilcoxon signed rank test.
