Although cluster randomisation has limitations, it reduced the scope for contamination between treatment groups as no general practice provided care for both telehealth and control participants.
In such cases we will combine several GN divisions into a single randomization unit to further reduce the scope for contamination.
Considerable attention has been devoted to the reliability of self-assessed health status and the scope for contamination by measurement error; and there is evidence of reporting bias [ 29- 31].
While the techniques are totally different, there is still considerable scope for sample contamination and sequence comparison, Table 2, suggests at least 7% of public data provided by The 1000 Genomes Project may have some Mycoplasma contamination.
Almost by definition, Next-Generation Sequencing is "massively parallel," generating many millions of individual sequence reads; therefore, there is considerable scope for cross-contamination to be detected.
As school districts in the U.S. consider remedial options, it is important to understand the scope of contamination.
Water quality must be maintained with frequent tests for contamination.
Controls for contamination were negative for ABLV.
Thirty-six outlets were evaluated for contamination persistence.
Plate cultures were visually inspected for contamination and liquid cultures were plated to check for contamination.
