For all gonorrhea patients, each provider was contacted to give permission to receive a data collection form by secure fax.
Given that data collection in the trial will run for a minimum of 12 months 100 GPs in each arm will be sufficient to detect a 10% change in prescriptions (p = 0.05, power = 0.80).
Once we are given the data collection forms, we need to understand those forms ourselves" (FGD November 2012).
Given that data collection was undertaken by staff from each site, or in some cases, questionnaires were mailed to participants, reasons for assistance were not systematically documented.
Referring to model development for mortality, given that data collection was not complete for all parameters, our intent was to use as simple a model as possible that provided rigorous, meaningful information.
'Guided' or 'Leitfaden' means that the interviewer prepares questions prior to the interview, which gives the data collection a structure that enables comparisons between different participants.
Given that the data collection was conducted in a relatively short period of time, the presence of any temporal changes could hardly have confused the data.

A standardized questionnaire was applied to the women having given birth for data collection, preferably during the first 24 hours after delivery.
Particular attention is given to primary data collection to build the environmental eco-profiles of four innovative composites.
