- days_blood: Number of days since the last menstrual period when the blood sample was taken
- weeks_eco: Number of weeks since the last menstrual period when the ultrasound was performed
- days_eco: Number of days since the last menstrual period when the ultrasound was performed
- tas: Systolic blood pressure (mmHg)
- tad: Diastolic blood pressure (mmHg)
- left_ut: Left uterine artery pulsatility index
- right_ut: Right uterine artery pulsatility index
- transvaginal: 1 if the ultrasound was performed transvaginally, 0 otherwise
- etnia: Ethnicity of the patient (afro, magreb, white, yellow)
- weight: Weight of the patient (kg)
- nulliparous: 1 if the patient has never given birth, 0 otherwise

Only nulliparous, old, previa, hta, and etnia are needed from the previous list. Additionally:
- meanut_mom: MoM value for mean uterine artery pulsatility index
- map_mom: MoM value for mean arterial pressure
- pappa_mom: MoM value for PAPP-A (pregnancy-associated plasma protein-A)
- plgf_mom: MoM value for PlGF (placental growth factor)
