Figure 1 . Flowchart of study patients
Figure 2 . Bland-Altman plots for comparing SpO2with SaO2 within the total study group. The X-axis represents the mean of SpO2 and SaO2((SpO2+SaO2)/2) and the Y-axis represents the difference between SpO2 and SaO2 (SpO2-SaO2). Red line shows the mean bias. Blue lines represent upper and lower limits of agreement at ± 1.96 SD.
Figure 3. Bland-Altman plots for comparing SpO2with SaO2 among patients with normal serum fibrinogen (<4.8 g/dL) (A) and with high serum fibrinogen (≥4.8 g/dL) (B). The X-axis represents the mean of SpO2 and SaO2 ((SpO2+SaO2)/2) and the Y-axis represents the difference between SpO2 and SaO2 (SpO2-SaO2). Red line shows the mean bias. Blue lines represent upper and lower limits of agreement at ± 1.96 SD. The mean difference was higher in patients with high fibrinogen levels than those with normal levels (5.07±2.44 vs 2.98±2.44, p <0.001).
Figure 4. Bland-Altman plots for comparing SpO2with SaO2 among patients with normal serum ferritin level (<228 ng/mL) (A) and with increased serum ferritin (≥228 ng/mL) (B). The X-axis represents the mean of SpO2 and SaO2 ((SpO2+SaO2)/2) and the Y-axis represents the difference between SpO2 and SaO2 (SpO2-SaO2). Red line shows the mean bias. Blue lines represent upper and lower limits of agreement at ± 1.96 SD. The mean difference was higher in patients with high ferritin levels than those with normal levels (4.88±2.46 vs 2.41±2.22, p <0.001).
Figure 5 . Bland-Altman plots for comparing SpO2with SaO2 among patients with normal lymphocyte count (>1.04 x 103/mm3) (A) and low lymphocyte count (≤1.04 x 103/mm3) (B). The X-axis represents the mean of SpO2 and SaO2((SpO2+SaO2)/2) and the Y-axis represents the difference between SpO2 and SaO2 (SpO2-SaO2). Red line shows the mean bias. Blue lines represent upper and lower limits of agreement at ± 1.96 SD. The mean difference was higher in patients with low lymphocyte count than those with normal levels (5.07±2.36 vs 2.66±2.39, p <0.001).
