Figure 1. Kaplan-Meier curve of disease resolution in cases of chronic spontaneous urticaria (orange) versus cold urticaria (blue). Cold urticaria was associated with a longer time to disease resolution when adjusting for sex and age at disease onset (Adjusted Hazard Ratio: 0.43 [95%CI: 0.21, 0.89], P<10-2). Confidence intervals are represented by the corresponding dashed lines.
