Nelle 1998.

Methods	Randomised controlled trial. Randomisation by sealed opaque envelopes.
Participants	Inclusion criteria Infants < 1500 g. Born by CS N = 19 babies Exclusion criteria
Interventions	Intervention: DCC Cord clamping after 30 secs and positioning of the infant 30 cm below placenta N = 11 babies Comparator: ECC Cord clamped immediately after birth N = 8 babies Additional information Gestational subgroup: < 32‐34 weeks' gestation Resuscitation with cord intact: not available Access to NICU: yes Length of delay: 30 secs Baby placed: low Uterotonics: no information UCM: n/a Comparison 1 DCC with neonatal resuscitation after cord clamping vs ECC (subgroup by gestation) Subgroup 1: < 32‐34 weeks' gestation Comparison 2 DCC with neonatal resuscitation after cord clamping vs ECC (subgroup by type intervention) Subgroup 2: DCC at < 1 min with baby low (+ gravity)
Outcomes	Outcomes: Mean arterial blood pressure, left ventricular output, mean cerebral blood flow velocity, Hb, Hct, systemic and cerebral Hb transport, volume expansion during the first 24 hrs.
Notes	No data for the review Setting: Germany Dates: not reported Declaration of interest: not reported Trial funding source: not reported Further information: Reported as abstract only There is lack of clarity as to whether this was an RCT or not. However, as the study provides no data for the review this issue was considered relatively unimportant. M Nelle kindly provided additional information regarding this study.
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Not described.
Allocation concealment (selection bias)	Unclear risk	Sealed, opaque envelopes (information provided by the author).
Blinding of participants and personnel (performance bias) All outcomes	High risk	No blinding. Not clear whether outcomes would be affected by lack of blinding. Other aspects of care may have been affected by lack of blinding.
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	No blinding. Not clear whether outcomes would be affected by lack of blinding. Other aspects of care may have been affected by lack of blinding.
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	Not clear whether full data were available for all participants.
Selective reporting (reporting bias)	Unclear risk	Reported in brief abstract.
Other bias	Unclear risk	Very little information on study methods.
