| Study characteristics | ||
| Methods | Randomised controlled trial | |
| Participants | Inclusion criteria:

| Interventions |
Intervention: Drager 76 phototherapy unit equipped with 6 special blue fluorescent lights (Philips TL 20 W/52BAM blue emission range 410 to 520 nm, maximum 460 nm). Four outer walls of the incubator draped with white cloth additionally N = 36 Control: Drager 76 phototherapy unit equipped with 6 standard fluorescent lights (Philips TL 20 W/52BAM blue emission range 410 to 520 nm, maximum at 460 nm) used without drapes N = 34 |
|
| Outcomes | Mean decrease in serum bilirubin after 24 hours of phototherapy Mean duration of phototherapy Adverse effects not reported |
|
| Notes | A third group included in the study used a different phototherapy unit. This group was not included in this review. Study was conducted in Germany | |
| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Unclear risk | Not described in the manuscript |
| Allocation concealment (selection bias) | Unclear risk | Not described in the manuscript |
| 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 | Unclear risk | No dropouts reported in the manuscript |
| Selective reporting (reporting bias) | Low risk | No protocol available. All expected outcomes and all outcome in the methods reported |
| Other bias | Low risk | No other sources of bias identified |
