Table 1 Characteristics at baseline and at birth for women who returned the questionnaires

From: Cord pilot trial, comparing alternative policies for timing of cord clamping before 32 weeks gestation: follow-up for women up to one year

Clamp ≥2 min + neonatal care with cord intact Clamp ≤20 s + neonatal care after clamping Clamp ≥2 min + neonatal care with cord intact Clamp ≤20 s + neonatal care after clamping

  1. Data are n (%), unless otherwise stated. sd = standard deviation
  2. aFor the one stage consent pathway written consent was given before randomisation. The two stage pathway was used for women when birth was imminent, with oral assent given before randomisation and written consent for follow-up after the birth
  3. bFor two, one twin known intrauterine death before randomisation
  4. cFor liveborn babies, two women in the clamp cord within 20 s group who returned both questionnaires had stillbirths
