Table 4. Simple linear regression between instruments and ANOVA for unstandardized predicted values.
| R | R 2 | Prediction equation | ANOVA for unstandardized predicted values | |
|---|---|---|---|---|
| Abbreviation: ANOVA, analysis of variance. | ||||
| Na + arterial vs. venous | 0.79 p < 0.001 |
0.63 p < 0.001 |
Na + Venous = 69.56 + 0.502*Na + Arterial | F = 163.68, p < 0.001 |
| K + arterial vs. venous | 0.64 p < 0.001 |
0.41 p < 0.001 |
K + Venous = 1.99 + 0.59*K + Arterial | F = 72.16, p < 0.001 |
| Cl – arterial vs. venous | 0.61 p < 0.001 |
0.38 p < 0.001 |
Cl – Venous = 58.90 + 0.41*Cl – Arterial | F = 60.48, p < 0.001 |
