The frequency of 3-tier (category) and 5-tier (level) classifications in each 10 min-segment of the last 60 min before delivery.
Fig 1.
Relationships of umbilical artery blood pH and BE at delivery with 3-tier classification in each 10 min-segment of the last 60 min before delivery (mean + standard deviation).
There were significant differences between category I and category II.
Fig 2.
Relationships of umbilical artery blood pH and BE at delivery with 5-tier classification in each 10 min-segment of the last 60 min before delivery (mean + standard deviation).
There were significant differences between Level 1 and Level 2.
