Subgroup analyses on gender and age at 30 min. Transcutaneous data obtained via the chest or forearm sensors were used (n = 272). Bars: SEM, *: P < 0.05, **: P < 0.01. a Comparison of biases between males (n = 168) and females (n = 104). Gender had no significant effects on PCO2 bias. However, the absolute values of male PO2 bias observed were significantly larger than those of female PO2 bias (Unpaired t-test). b Comparison of biases among 4 age groups: 20–39 years (n = 11), 40–59 years (n = 12), 60–79 years (n = 138), and ≥ 80 years (n = 111). PCO2 biases in young adults (20–39 years) were significantly lower than in the 2 groups of 40–59 years and ≥ 80 years. However, there were no significant differences in PO2 bias among the four groups (ANOVA with Tukey’s pot-hoc test)
