Could this be subject to bias?
The probability of the study result being subject to bias while interpreting -------- it's a YES

Probability of Leukemia
A. Among traced group
= 4/1,870 persons.
B. Among self-reported group
= 4/443 person.
We can deduce
A higher rate of occurrence in self-reported group which could be causesd by fear of leukemia occurrence or suspicion of their previous exposure at atomic sites
