Furthermore, as the current research project collected data nationally, in-person data collection was impossible.
Telephone interviews and in-person data collection at WIC offices occur at 3 time points: baseline, immediately, and 3 months after the 16-week intervention.
Two in-person data collection sessions will occur for each patient, one at the baseline visit and the other at 1 year following TKA.
Ongoing in-person data acquisition at an expanded cohort of community health centers and surrounding villages will enable improved statistics as to the rate of preterm births, term births, fresh stillbirths (neonatal demise), and macerated stillbirths [ 22- 25].
During the in-person data collection visits, participants were provided with a laboratory requisition to have their blood drawn at baseline and again at 3 and 6 months after study enrollment.
Finally, while advances in Internet medical education technology allow for greater efficiency and access to a bigger population, methods for online observational data collection are subject to similar limitations as in-person data collection.
Non-responders to SATSA questionnaire or in-person data collection are over-represented among the dementia cases; thus, these numbers should not be used to form a prevalence rate.
When in-person data collection is required, there are often efficient approaches to collecting data that are superior to geographically based exposure estimates through self-report, environmental measurements, or biologic monitoring, although this might not always be the case, for example, where historical exposure estimates are required.
Each data collector also participated in a 2-day, in-person, data collector training program led by the Principal Investigator, which reviewed: 1) human subjects ethics principles and procedures, 2) recruitment, sampling and consenting procedures, and 3) instruments and protocol for delivery.
These data suggest that the FFQ data in this population may have been more prone to error than the in-person interview data.
But they have not offered the same level of support for Clinton in the numbers expected, according to an analysis of early in-person voting data, angering a prominent African American Democratic congressman who said he had been "screaming for months" for the Clinton campaign to spend more money on the black community in the state.
