Fig. 3
Bland-Altman plot showing the difference of irradiance levels of each phototherapy device, with curtains compared to without curtains, for those phototherapy devices that had irradiance levels below 30 μw/cm2/nm. Each phototherapy device presents one dot, the mean (SD) difference was 1.05 (2.08) μW/cm2/nm higher when using curtains (P = 0.370)
