In the original article, there was a mistake in Figure 1 as published. The color shade of the Kaplan-Meier survival curves was confused between the group with surgery and radiotherapy for the US data. The corrected Figure 1 appears below.
Figure 1.
Kaplan–Meier (A) comparing surgery vs. radiotherapy (radiotherapy = reference) and (B) hazard survival plot of prostate cancer patients from German and US cancer registries. Lines indicate the year of diagnosis specific (2005–2013) conditional hazard for radiotherapy (risk to die in the following month, blue) and surgery (red) from Kaplan–Meier plots. Thick lines refer to the smoothed average of year-specific hazard in patients treated with radiotherapy and surgery, respectively.
