In Reply: Dr Wang and colleagues note that several factors that may alter the risk of cancer were not listed in the baseline table in our article, such as diabetes and use of statins and antidiabetic drugs. This population was healthier than the general population, as demonstrated by the low smoking rates. Rates of diabetes were not included in Table 1 because they were very low, in the single digits. On the other hand, the rate of cancer screening was high. This is illustrated by the high proportion of total cancers that was due to prostate cancer.
