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

aMean genotype completion rates were not significantly different (P = 0.197, Kruskal-Wallis test) across multiplexing levels. However, there was significant, albeit weak, correlation between mean genotype completion rates and multiplexing levels (coefficient = −0.163, P = 0.032).bMean genotype completion rates were not significantly different (P = 0.168, Kruskal-Wallis test) across multiplexing levels. However, there was significant, albeit weak, correlation between mean genotype completion rates and multiplexing levels (coefficient = −0.155, P = 0.041).cMean genotype completion rates was not significantly different (P = 0.078, Kruskal-Wallis test) across multiplexing levels. There was no significant correlation between mean genotype completion rates and multiplexing levels either (coefficient = 0.045, P = 0.599).dP values for comparison of mean genotype completion rates across three matched sample groups by Friedman test.eP values for matched pairwise comparison of mean genotype completion rates by Wilcoxon signed rank test.
