  1. Effect sizes (Cohen’s d) between the measurements and gold standard values were also calculated. Significance level was set at α = 0.05. See Table 2 for definitions of the parameters. The measurement errors were determined as the differences between the measurements and the corresponding standard values, and represented as percentages of the standard values
