evidence provided from studies in iran points to a possible bias in application of the standard epi cluster sampling procedure, when carried out in populations with highly variant birth rates, tends to over-represent the low birth rate, i.e. higher socio-economic, strata, and if the entity under study shows significant socio-economic gradient, then the estimates arrived at by this method might ...

The degrees of significance, however, are often quite low, and the results are possibly confounded by effects, such as lifestyle-related factors, which may have a strong impact on cancer morbidity/mortality and thus result in false-positives. Here, we di...
