Some data exchange standards are now being designed with data verification in mind, and a prime example is the BioPAX standard for pathway data sharing, which is based on formalized knowledge in OWL [ 86].
The average time for browsing an ECG report without data verification in the cloud is approximately 5.65 ± 0.38 secs, but the average time for browsing the file with data verification in the cloud is approximately 6.28 ± 0.13 secs.
Data entry error rates, nature of the errors, and any quality control issues found during source data verification were discussed with the site staff and principal investigators.
Fourth, an ECG report generator, and a data encryption with data verification program represented by two Work roles are used to safeguard patients' ECG reports in the Azure database.

Overall, there was good compliance with the defined diagnostic criteria with source data verification performed for all sites; this ensured that clinical diagnosis of preeclampsia was largely consistent between centers.
Missing data were reviewed with source data verification.
On-site monitoring with source data verification is performed in ≥20% of centres.
Field testing High-quality data can be obtained thanks to thorough and tested field procedures, combined with rigorous data verification.
Such information was collected as part of large multicenter study with independent data verification and negligible missing data.
In 20% of participating centres, on-site monitoring of the centres will be performed with source data verification.
