Figure 1 Results of stratified analyses on the association between current smoking at baseline and risk of basal cell carcinoma. The square represents the HR of the association between current smoking and risk of basal cell carcinoma, and the lines represent the 95% confidence intervals of the association. CI, confidence interval; HR, hazard ratio. Journal of Investigative Dermatology 2017 137, 1700-1708DOI: (10.1016/j.jid.2017.03.027) Copyright © 2017 The Authors Terms and Conditions

Figure 2 Results of stratified analyses on the association between current smoking at baseline and risk of squamous cell carcinoma. The square represents the HR of the association between current smoking and risk of basal cell carcinoma, and the lines represent the 95% confidence intervals of the association. The upper range of the confidence interval for some strata was too large and was truncated while trying to keep the same scale. CI, confidence interval; HR, hazard ratio.
