6. Support "live updates" of primary study data contained within an ancillary study.
The goal of this review is to bring together an update of studies on gene expression in the mammary gland, highlighting the possible influence of cow management on epigenetic mechanisms.
The vinyl chloride studies most often cited today — including a major study soon to be published — in fact are updates of a study first done in 1974.
Recent updates of this study reported excess mortality in association with exposures to particulate matter of aerodynamic diameter ≤10 μm (PM10), whereas no independent associations with gaseous pollutants were observed (Dominici et al. 2002, 2003).
Throughout the day, data are transferred from the field staff's personal data assistants (PDAs) to a supervisor's PDA to prevent data loss and to allow for multiple updates of the study database throughout the day.
As well as updating programmes of study, we need better teacher training, higher standards, and continual assessment of what pupils are being taught.
A similar hazard ratio (HR) in favour of eribulin was observed in patients with triple-negative breast cancer in the initial analysis of Study 305/EMBRACE and Study 301 (HR 0.71 and 0.70, respectively) [ 10], but not in the updated analysis of Study 305/EMBRACE.
The European Journal of Epidemiology publishes quite frequently descriptions of new studies and presents also occasionally updates of these studies' objectives and design [ 3, 40, 41, 79– 89].
We limited the review to the most recent updates of occupational studies, although we include findings from earlier reports where results have changed materially with successive updates.
In an attempt to enhance the cohort response rate, we send quarterly newsletters to all our study doctors providing them with an update of the study progress, and encouraging them to promote the cohort study.
