Abbreviations: GA = Gestational Age; BW = Birth Weight; BE = Base Excess.

^aVD = Vaginal Delivery; IVD = Induced Vaginal Delivery; EVD = Emergency Vaginal Delivery; ElVD = Elective Vaginal Delivery; ECS = Emergency Caesarian Section; OVD-VE = Operative Vaginal Delivery with Vacuum Extractor.

^bAn arbitrary classification scale was used to codify Apgar10min, pH and BE

Code 0 = Apgar10min ≥ 7; pH ≥ 7,20; BE ≥ -12.

Code 1 = 5 < Apgar10min < 7; 7 < pH <7,20; -17 < BE < -12.

Code 2 = Apgar10min ≤ 5; pH < 7; BE ≤ -17.
