Rashmi 2015.

Study characteristics
Methods	Randomised controlled trial
Participants	Inclusion criteria: Term infants > 2500 grams, SB between 300 and 340 micromol/L, aged 48 hours to 14 days Exclusion criteria: Infants with haemolysis Infants on phenobarbitone or herbal preparations Mean (SD) age in days at recruitment: Intervention = 4.47 (1.4) Control = 3.80 (1.26) Mean (SD) body weight in kg of participants: Intervention = 2.19 (0.31) Control = 2.23 (0.43)
Interventions	Intervention: standard phototherapy with white reflective curtains around the phototherapy unit (15 infants) Control: standard phototherapy without reflective curtains (15 infants)
Outcomes	Mean SB at 24 and 48 hours Mean duration of phototherapy in hours
Notes	Nature of reflective material used not reported. Study conducted in Uttarakhand, India. Only one outcome reported. Data on adverse effects (skin turgor, skin rash, loose stools, body temperature, pulse respiration, blood pressure) collected but not reported
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	"Newborns were randomly assigned into experimental and control groups" ‐ exact method of random sequence generation not reported
Allocation concealment (selection bias)	Unclear risk	Not reported
Blinding of participants and personnel (performance bias) All outcomes	High risk	Blinding not described Comment: we judged that blinding of parents and caregivers would not be possible
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	30 patients randomly assigned to 2 groups. Results tables provide data for 30 neonates (15 per group). We judged no loss to follow‐up
Selective reporting (reporting bias)	High risk	Adverse effects monitored but not reported
Other bias	Unclear risk	None detected
