Probability of non-clearance with the two lamps. Survival curves showing the probability of non-clearance of psoriasis during treatment with narrowband UVB (TL-01) (dashed lines) and selective broadband UVB (UV6) (solid lines). The stepped lines are Kaplan–Meier plots, with censored observations indicated by the small vertical tick marks. The smooth curves are fitted Weibull curves for each lamp, plotted at the mean values of the stratifying factors.
