Linear regression models were run for each of the five data sets that contained the measured and imputed concentrations.
Rates of allergic sensitization were not statistically different between children assigned LUR estimates (16%) and those who had imputed concentrations (13.5%).
To obtain population based estimates of risk, we first imputed concentrations for participants without measured prostate specific antigen 623 men without a diagnosis of prostate cancer who were not selected as controls by randomly sampling concentrations with replacement from cancer-free controls.
In statistical analyses, we imputed concentrations < MDL as the MDL divided by the square root of 2. For congeners that were detected in > 70% of samples, we calculated Spearman correlation coefficients (rS) to determine the associations between continuous household dust, hand wipes, and urine levels (BDCIPP and DPHP only).
Assignment of air pollutants to risk categories involved first setting category boundaries based on health-related toxicity values, and then using these values to impute concentration thresholds for each of the five categories.
If NOx could not be calculated because of failed geocoding of an address, we imputed the concentration from that calculated at the preceding address, or that at the subsequent address if the NOx concentration was missing for the first address.
If air pollution could not be calculated because of failed geocoding of an address, we imputed the concentration calculated at the preceding address.
If NOx, NO2, and NO could not be calculated because of failed geocoding, we imputed the concentration calculated at the preceding or subsequent residential address of the cohort member as previously described (Raaschou-Nielsen et al. 2011).
We imputed DAP concentrations that were reported as zero by choosing a random number between zero and the lowest nonzero value for that metabolite.
A value of 0.5 μ g/L, the midpoint from 0 to the limit of detection (LOD; 1 μ g/L) was imputed for concentrations below the LOD.
In fact, imputed postmenopausal concentrations of estradiol improved the discriminatory accuracy of the log-incidence model for breast cancer risk prediction developed by Rosner and Colditz [ 40], although only modestly.
