a
The p values adjusted according to Bonferroni show whether normalized relative mean differences were significantly different from zero.
b
Sensitivity to increased blood pO2 was labeled in the package inserts.
c
Potential influences of pO2 on measurement results were not labeled in the user manual/package inserts.
