The dye concentration was quantified by linear calibration with standards.
The fluorescence of the mixtures was measured and the dye concentration quantified by linear calibration with matrix-matched standards.
Linearity and range were determined by linear regression analysis of the calibration curve with 1/x-axis weighting.
Only completely resolved chromatographic peaks area ratios were compared with a linear calibration curve generated by analysis of standards of 6 different concentrations in triplet.
Calibration curves were constructed by linear regression analysis of the peak area ratios of C16:0/C12 0 versus the amount of C16:0 sulfatide.
Cytokine levels were determined by linear regression analysis using a standard curve generated with the supplied calibration material in case of EBV IL-10 or the commercial recombinant HCMV IL-10 protein standard (R&D Systems), respectively.
A calibration curve was obtained by plotting peak areas of ten ΔDi-HA standards against their concentrations followed by linear regression analysis calculated using the method of least squares.
Correlations between continuous variables were tested by linear regression analysis.
bDetermined by linear regression analysis.
Associations were assessed by linear regression analysis.
