Sentence examples for misclassification of events from inspiring English sources

The fact that the results were consistent across the NAFLD spectrum supports the fact that misclassification of events is unlikely to explain our findings.

3 25262727 Several trials lacked independent adjudication of events, therefore bias in either direction cannot be excluded, including bias towards the null owing to non-differential misclassification of events or assessor bias in trials without independent adjudication.

The broader definition of the outcome in the UK study might explain the difference between that study and ours, as the risk of misclassification of events probably is lower in the present study.

Although the Clinical Practice Research Datalink database has been validated and used extensively for epidemiological research, including the relations between blood pressure, diabetes, and vascular disease, 11 18 the risk of misclassification of events may be greater than in a traditional cohort study.

18 The advantages of central adjudication include systematically applying the definition of an event, reducing the possibility of differential misclassification of events, giving greater confidence in the validity of the study results, and by including suitable triggers, potentially identifying events that are missed by local investigators.

In studies based on administrative data, misclassification of events may be assumed to be non-differential with respect to exposure, providing a bias in the hazard estimate toward the null value that might obscure an association between exenatide and vascular risk.

Misclassification of outcome events is also possible in administrative databases because these codes have not been directly validated.

The bias due to nondifferential misclassification of event-days is likely small but will be toward the null if present, and the power of the study could be reduced because of missed events.

We attempted to reduce the potential for misclassification of event-days by including only data from monitoring periods during which the monitor was used for at least two-thirds of the days.

Because we capture actual treatment received by the patient from retrospective review, but not any planned treatments that were not carried out due to intercedent adverse events, misclassification bias of events may have occurred.

As a consequence of this, misclassification of disease events in animal disease recording systems based on veterinary treatments could be differential, i.e. occur with different magnitudes and with different directions.
