In cases where a practice shifted from one group to another during the baseline data collection timeframe, we assigned that practice to the group in which they spent the majority of the year in.
Typically, per UMUC3 nucleus, 80 or more spots were resolved, of which 40 to 60 unambiguous telomeres could be tracked for extended periods within each total 200-second data collection timeframe (see C-E in Additional file 1).
They may also be attributed in part to different data collection timeframes, i.e., El Cuete Phase I data was collected in 2004 while El Cuete Phase III qualitative data were collected between October 2006 and January 2008.
Since the delivery of the IDOCC program was staggered in the stepped wedge implementation approach, the baseline data collection timeframes varied among steps: Step I: 2007-2008, Step II: 2008-2009, and Step III: 2009-2010.
While this may have increased recall of responses to questionnaire items, in the interest of limiting measurement differences due to actual HRQoL changes, we chose to undertake data collection within this timeframe.
However, diarrhea was reported much less frequently in 2005 than 2008 (16% and 21% respectively), despite data collection during similar timeframes for both survey years.
340 341 The protocol should describe the procedures for and frequency of harms data collection, the overall surveillance timeframe, any instruments to be used, and their validity and reliability, if known.
The aim of these meetings was to introduce the research objectives, target population, rationale and history of the questionnaire, give detailed discussions of each item in the questionnaire, and plan for instrument translation, adaptation, pre-testing and data collection within the allocated timeframe, which was scheduled to start in March of that year.
Aggregating studies that have used different methods of data collection and somewhat variable timeframes for headache (during the last year or less), the present survey indicates that more than 50% of the population in Europe are current headache sufferers, and almost 15% suffer from migraine.
However, it may be possible that moisture generated has not fully condensed to recover the heat of vaporization given up, within the timeframe of data collection.
The study outcomes, measurement tools and timeframe for data collection is summarised in Table 4.
