Figure 1 Trial profile Two infants in the FSPT group received IEPT on one treatment day, and an infant in the IEPT group received 3 days of FSPT. Treatment days were not assessable for efficacy if the infant received <4 h phototherapy or if either TSB measurement was missing. These issues often occurred on the same day. Furthermore, because most infants received more than 1 day of treatment, the number of infants completely excluded from the efficacy analysis (eight infants in the FSPT and four in the IEPT group) is much lower than the number of treatment days excluded. FSPT=filtered sunlight phototherapy. IEPT=intensive electric phototherapy. TSB=total serum bilirubin. *Neonates diagnosed with primarily direct hyperbilirubinaemia were excluded because phototherapy is contraindicated in direct hyperbilirubinaemia.

Figure 2 Median irradiance by time of day across all enrolled neonates and days The irradiance data during the first 50 days of the study were unusually variable, probably because of training issues, and were excluded from this figure. For FSPT, median irradiance is represented by the dots (error bars represent IQR). For IEPT, the solid horizontal line represents the median (dotted horizontal lines represent IQR). FSPT=filtered sunlight phototherapy. IEPT=intensive electric phototherapy. The Lancet Global Health 2018 6, e1122-e1131DOI: (10.1016/S2214-109X(18)30373-5) Copyright © 2018 The Author(s).

Figure 3 Rate of change in TSB as a function of initial morning TSB for all assessable treatment days The dotted line shows zero change. The red and blue lines are linear regression fits for the FSPT and IEPT groups, respectively. TSB=total serum bilirubin. FSPT=filtered sunlight phototherapy. IEPT=intensive electric phototherapy.
