Data are % (95% CI).
*Adverse outcome defined as death, cerebral palsy with Gross Motor Function Classification System level 3–5 or Bayley-III cognitive and/or motor composite score <85.
†Moderately/Severely abnormal MRI defined as moderate/severe BGT score and/or absent PLIC and/or severe WM score.
BGT, basal ganglia and thalami; FMs, fidgety movements; NPV, negative predictive value; PLIC, posterior limb of the internal capsule; PPV, positive predictive value.
