Devpura 2017.

Study characteristics
Methods	Randomised controlled trial
Participants	Inclusion criteria: All term > 37 weeks neonates born in hospital between November 2011 and October 2012 who satisfied the following criteria: Age > 24 hours and < 14 days Apgar score at 5 minutes > 6 TSB < 357 μmol/L Neonates with ABO incompatibility but negative direct Coombs test (DCT) with no evidence of haemolysis on peripheral blood smear Exclusion criteria: Hyperbilirubinaemia requiring exchange transfusion Evidence of haemolysis in peripheral blood film Rh haemolytic disease Positive DCT G6PD deficiency Major congenital malformations Culture‐positive sepsis Need for intensive care Conjugated hyperbilirubinaemia Mean (SD) age in days at recruitment: Intervention = 2.84 (0.53) Control = 2.96 (0.70) Mean (SD) birth weight in kg of participants: Intervention = 2.78 (0.36) Control = 2.79 (0.26)
Interventions	Intervention Experimental group: Single phototherapy with white reflective plastic curtains on 3 sides Control group: Single‐surface phototherapy
Outcomes	Fall in SB at the end of 12 hours, 24 hours Rate of fall of serum bilirubin in first 12 hours and between 12 hours and 24 hours Duration of phototherapy (hours)
Notes	Study done at a tertiary care institution in Rajasthan, India. SB reported in mg/dL
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	"...randomly assigned ... by paper chit method". We judged this description to show unclear risk
Allocation concealment (selection bias)	Unclear risk	Not reported
Blinding of participants and personnel (performance bias) All outcomes	High risk	Participants: neonates by definition blinded, but parents not blinded. Clinicians/Nurses not blinded. The type of intervention may have influenced handling of the baby by parents and healthcare providers
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Not reported. We judged bilirubin measurement to be an objective measurement not affected by lack of blinding
Incomplete outcome data (attrition bias) All outcomes	Low risk	Three patients in the intervention group and 4 in the control group excluded from analysis (i.e. 6.5% of participants not included in analysis)
Selective reporting (reporting bias)	Low risk	Protocol not available. All expected outcomes reported
Other bias	Low risk	No other source of bias identified
