A keywords analysis revealed that groundwater quality and contamination, effective research technologies, and treatment technologies for water-quality improvement were the main research areas in the study period.
The fact that the time investment in the intervention group was much higher, made us expect that contamination of research conditions would be limited.
Adolescents were the unit of analysis and to minimize contamination between research conditions, we randomized schools to intervention or control condition (lessons as usual) with allocation ratio of 1 1.
It was not possible to blind women to allocation group; however, to minimise contamination, a research midwife was employed at each centre, and antenatal staff were kept blinded to the treatment allocation and the actual content of the decision aid.
The details of a potentially dangerous virus contamination that affected research labs in four European countries may remain shrouded in mystery.
The increased demands for improved technical performance and/or minimized environmental contamination have motivated research on the development of new PU coating systems.
Third, in order to minimize contamination bias, the research assistant responsible for collecting data related to RADAR was blinded to the delirium status of patients/residents.
A permanent MM epidemiologic surveillance system, based on a national register (ReNaM), has been established in Italy to estimate incidence rates, investigate asbestos exposures, identify any possible underestimated or unknown sources of asbestos contamination, and promote research and reclamation programs.
Recruitment through General Practice Networks ensured participating HCPs, and subsequently patients, in each arm of the study would be geographically isolated and thus ensured a reduction in the potential for contamination between the research arms.
These observations further suggest a Normal-like control lacks the sensitivity and specificity required for inclusion in the Prosigna in vitro diagnostic test, but is suitable for identifying samples with substantial normal RNA contamination in a research setting where pathology review and macrodissection may not always be feasible.
