Each short term family planning user who was visiting selected health centers during the study period were interviewed until the allocated sample size to every facility was reached.
The study participants were selected every eight (8th) household intervals, by dividing the total number of households to the allocated sample size.
A consecutive sampling method was then employed to select eligible cases and controls until the allocated sample size was filled from the respective health facilities.
The stratification was done during the selection and where randomly selected number of patients in a stratum got at least half of the allocated sample size the subsequent random selections will only be valid if is for the other stratum.

A meaningful explanation of the probability estimate (hat{f} x,y)) is that, it allocates sample probability of smoothness parameter for each sample x i and y i, and the probability estimate is the sum of those sample probabilities.
For example, Neyman allocation is a method used to allocate samples based on the stratum variances and population sizes, assuming similar sampling costs in the strata, and given a fixed total sample size (Cochran 1977).
While the pollution source indicators used to allocate sampling sites were consistent with the LUR literature, we did not find strong overall relationships between measured pollutants and traffic density or emissions-weighted proximity to industry.
