Lahiri 2016.

Study characteristics
Methods	Randomised controlled trial
Participants	Term infants between 24 hours and 10 days of age, exclusively breastfed, birth weight > 2500 grams, SB < 340 micromol/L. Infants with haemolysis excluded Mean (SD) age in days at recruitment: Intervention = not available Control = not available Mean (SD) birth weight in kg of participants: Intervention = 2.72 (0.37) Control = 2.69 (0.47)
Interventions	Intervention: phototherapy (6 compact light sources ‐ 4 blue and 2 white) with reflective curtains (white cotton sheets with inner reflective surface) Control: phototherapy with a similar phototherapy unit without any curtains
Outcomes	SB at 4, 12, and 24 hours Mean SB decline Duration of phototherapy Mean spectral irradiance Adverse effects not reported
Notes	Conducted in Calcutta, India, from June 2011 until May 2012
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Computer‐generated random sequence after consent obtained
Allocation concealment (selection bias)	Low risk	"... allocation mailed to researcher after inclusion in the study..."
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	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	Two (out of 100) excluded from control group post randomisation due to G6PD deficiency. All other infants in the study accounted for
Selective reporting (reporting bias)	Unclear risk	No protocol available. All expected outcomes reported
Other bias	Low risk	None detected. No adverse effects reported
