Among children born moderately or late preterm, small for gestational age, malformations, elective and emergency caesarian section and admission to neonatal care were all associated with cerebral palsy (all p values &lt;0.05), whereas among children born very preterm no factors were significantly associated with the outcome (all p values&gt;0.05).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Our results support and strengthen previous findings on factors associated with cerebral palsy.
