Djokomuljanto 2006.

Study characteristics
Methods	Randomised controlled trial
Participants	Inclusion criteria: Conducted at a single centre in Malaysia Term newborns with uncomplicated neonatal jaundice presenting in the first week of life, with levels of bilirubin requiring phototherapy according to Malaysian CPG based on AAP guidelines Exclusion criteria: Babies with serum bilirubin levels close to the exchange transfusion limit Mean (SD) age in days at recruitment: Intervention = 4.30 (2.08) Control = 4.45 (2.07) Mean (SD) body weight in kg of participants: Intervention = 3.01 (0.49) Control = 3.07 (0.44)
Interventions	Single phototherapy with reflective curtains vs single phototherapy
Outcomes	Mean decrease in SB after 4 hours phototherapy Median duration phototherapy (hours) Side effects including hypothermia, hyperthermia, dehydration, weight loss, skin rash, bronze discolouration
Notes	Breastfeeding not reported. Study author contacted for mean SB at 24 hours and replied that this was not available Study performed in Kelantan, Malaysia, from 1 September 2005 until 1 December 2005
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Block randomisation generated via computer software by a staff member who was not involved in the study (information provided by study authors)
Allocation concealment (selection bias)	Low risk	"The investigators were blinded to the allocation until the inclusion of the infant in the study had been confirmed"
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	Low risk	"The laboratory staff were blinded to the study"; we judged bilirubin measurement to be objective. Lack of blinding of participants and staff unlikely to have an effect on the outcomes reported (changes in bilirubin levels)
Incomplete outcome data (attrition bias) All outcomes	Low risk	Dropout rate < 5%
Selective reporting (reporting bias)	High risk	In the methods, stated that bilirubin levels taken after 4, 8, 16, and 24 hours, but only changes in levels after 4 hours reported
Other bias	Low risk	No other sources of bias identified
