Sentence examples for misclassification of current from inspiring English sources

Another limitation of the study is possible misclassification of current asthma status.

To explore the effect of potential misclassification of current exposure on the estimated RRs, the duration of the current exposure time window was shortened to 30 days prior to the index date for all cases and controls.

Secondly, we cannot rule out bias due to social desirability or imperfect recall, which could have led to under-reporting and thus to misclassification of current or former smokers to the never smoker category and thus to an underestimation of risk estimates.

The inclusion of former smokers is potentially problematic as historical exposure may be dominated by the former smoker's own previous smoking behaviours, and misclassification of current smoking status may be particularly likely in this group, leading to a residual confounding effect.

Our finding that former smokers who had stopped smoking less than 24 years ago had statistically significantly lower mammographic density when compared with never smokers may partly be due to misclassification of current smokers as former smokers, as well as due to residual confounding.

While human half-lives of PFOA and PFOS are long (up to 8.5 [ 49] and 5.4 years [ 50], respectively), random misclassification error due to the use of current PFC levels as proxy measures of etiologically relevant exposures may have biased our results toward the null.

If the prenatal period and early childhood, when the developing brain may be more susceptible, are the critical periods for insult from PFC exposure, then random misclassification error resulting from the use of current PFC levels as proxy measures of etiologically relevant exposures may have biased our results toward the null.

In addition, nondifferential misclassification of pesticide exposure in the current study is likely to occur and, if apparent, can lead to an underestimation of the risk of DNA damage.

At a given point in time, a large proportion of the most recent BMIs are unlikely to reflect current BMI; consequent BMI misclassification might be reduced by employing model-based imputation of current BMI.
