The results showed that age of home ( p = 0.012) and ln(creatinine levels) ( p = 0.004) were significant predictors and sampling season, time spent outside, and owning a pet dog or cat were marginally statistically significant predictors of ln(urinary PCP level), together explaining 29% of the variability in PCP concentrations in the children’s urine samples.
