Pearson correlation coefficient (P < 0.001, r = 0.95) of the raw data (N = 130 samples from 13 steers), with the glucose concentration as measured by the glucometer on the y-axis (Precision Xtra; Abbott Diabetes Care, Inc., Mississauga, ON, Canada) plotted against the plasma preserved in sodium fluoride tubes and analyzed in a laboratory with a colorimetric assay (Stanbio Glucose LiquiColor (Oxidase) Procedure, Stanbio Laboratory, Boerne, TX, USA) on the x-axis.
Fig 2.
Bland-Altman plot of the raw data (N = 130 samples from 13 steers), with the mean glucose concentration as measured by the glucometer (Precision Xtra; Abbott Diabetes Care, Inc., Mississauga, ON, Canada) and the plasma preserved in sodium fluoride tubes and analyzed in a laboratory with a colorimetric assay (Stanbio Glucose LiquiColor (Oxidase) Procedure, Stanbio Laboratory, Boerne, TX, USA) on the x-axis, plotted against the difference in glucose concentrations determined by the glucometer and the laboratory on the y-axis.
The mean difference is represented by the solid line (mean = 4.6) and the 95% confidence limits are represented by the dashed lines.
Fig 3.
Bland-Altman plot of the log transformed data (N = 130 samples from 13 steers), with the mean glucose concentration as measured by the glucometer (Precision Xtra; Abbott Diabetes Care, Inc., Mississauga, ON, Canada) and the plasma preserved in sodium fluoride tubes and analyzed in a laboratory with a colorimetric assay (Stanbio Glucose LiquiColor (Oxidase) Procedure, Stanbio Laboratory, Boerne, TX, USA) on the x-axis, plotted against the difference in glucose concentrations determined by the glucometer and the laboratory on the y-axis. The mean difference is represented by the solid line (mean = 0.03) and the 95% confidence limits are represented by the dashed lines.
