Alternatives: "an inability to confirm" or "a lack of verification."
Importantly, we used the same bioinformatics pipeline in the original analysis and in the validation procedure: that is, the failure to validate most cases of putative superinfection did not arise from the (lack of) sensitivity of the original phylogenetics analysis, but due to erroneous entries (sequence or sample mix-up) in the original database.
27 36 37 This probably reflects a combination of the inherent over-optimism of data-driven model predictions based on small datasets, 15 19 21 38– 40 failure to validate models and/or scores in an independent dataset, 15 19 and spectrum bias arising from the use of case control designs.

Failure to validate models, the few comparative studies, and lack of consideration given to uncertainties in measurements and parameters are the most outstanding drawbacks.
Our failure to validate three of the selected targets (ELL3-AS, DNM2 and C12orf48; Figure-2 C, E, and G) can in part be explained by our validation criteria being more stringent than our criteria for selecting transcripts for validation.
The failure to validate the expression microarray results by qRT-PCR results may partially reflect technical differences between the platforms.
Failure to validate the regulatory relationships of the remaining sRNA target pairs by microarray data analysis might attribute to several embedded factors.
