Fig. 4
Bland-Altman plot showing the difference of irradiance levels of phototherapy with curtains compared to without curtains, for phototherapy devices that have irradiance levels above 30 μw/cm2/nm. Each phototherapy device presents one dot. The mean (SD) difference was 2.58 (4.37) μW/cm2/nm higher when using curtains (P = 0.572)
