Real-time PCR efficiencies (E) for each reaction were calculated from the slope of the standard curve using the equation E = 10 -1/slope -1 as implemented in the BioRad CFX manager V1.5 software, with 100% efficiency as an indicator of a robust assay.
Recent research using blood cotinine levels as an indicator of exposure to ETS shows a robust inverse relationship between postnatal cotinine levels and cognitive scores (math and reading) in 6- to 16-year-old children.

While HIA predictions alone would not be sufficient for a definitive assignment of pathogenicity, except for some key residues with critical functional roles such as 255G>A (m.902G>andand 533U>G (m.1180T>G), the method does provide a robust indicator of disruptiveness for a large group of mutations lacking direct evidence regarding their role in mitochondrial dysfunction.
