Format

This data frame contains the following columns:

folate

a numeric vector, folate concentration (microgram per liter).

ventilation

a factor with levels N2O+O2,24h: 50% nitrous oxide and 50% oxygen, continuously for 24 hours; N2O+O2,op: 50% nitrous oxide and 50% oxygen, only during operation; O2,24h: no nitrous oxide but 35%–50% oxygen for 24 hours.
