Barriers reported in two or more high-quality studies qualified as stronger evidence.
These libraries contributed to more than 25.6 million raw small-RNA reads total, among which 23,468,606 (>91% of the total) were adapter-trimmed, high-quality reads (qualified reads, Additional file 2: Table S1A).
Overall ~33 million (>90%) of raw sequencing reads from mRNA genes, or RNA-seq reads, were high-quality (or qualified) reads, among which more than 80% could be mapped to the Cassava reference genome (http://phytozome.net) allowing one mismatch (Additional file 1: Table S1).
Correspondingly, four small-RNA libraries for the NC, CA, CCA and CS conditions contributed more than 25.6 million raw small-RNA sequencing reads (see Methods, sequencing data in NCBI/GEO, accession # GSE52178), among which 23,468,606 (>91% of the total) were adapter-trimmed, high-quality reads (qualified reads, Additional file 1: Table S2A).
This was pointed out by Guyatt et al, 7 who developed the GRADE system, which first qualifies evidence derived from RCTs as high quality evidence while observational studies are qualified as low quality evidence.
To qualify as high quality evidence, more than 75% of the RCTs within a comparison had to be judged to have no limitations of study design, have consistent findings among multiple studies, present direct (generalizable) and precise data, without known or suspected publication bias.
Last week, EC Commissioner Franz Fischler announced that in the future European farmers will be required to fulfil high quality and environmental standards in order to qualify for subsidies.
It becomes clear that not all criteria have to be met for information material to qualify as being of high quality.
Given the strategic importance (and scarcity) of doctorally qualified nurses, more research is needed to ensure a high quality doctoral provision and a satisfactory student experience.
She says the biggest single challenge in the future is recruiting more mental health nurses: "You cannot provide high-quality care without qualified, dedicated staff".
