After manual selection of the cell area based on bright-field images acquired during the data collection phase, the fluorescence images corresponding to the selected cells were band-pass filtered to remove the low-frequency modulated background and high-frequency camera noise typically in our image data.
We are grateful to the management and staff of Mbale Regional Referral Hospital for the valuable support rendered to us during the data collection phase of the study.
This 'problem' was handled statistically by selecting a distribution that fitted the data [ 18] or by cutting off the extreme values due to suspected non-compliance "based on the subjective opinion of the investigators' during the data collection phase" [ 17].
We are grateful to the management and staff of all study institutions for the valuable support that you rendered to us during the data collection phase of the study.
We must have consumed hundreds of cups of tea during the data collection phase, but the opportunity to interact and chat informally provided valuable insights and enhanced our standing overall.
The mean FPG level determined before breakfast during the data collection phase was significantly lower in the IDeg administration period than in the IGlar administration period (7.74 ± 1.76 vs 8.56 ± 2.06 mmol/l; p = 0.04) (Fig. 2a, b).
Apart from debriefing between the first and second authors during the data collection phase, team members independently reviewed the transcripts and regular team meetings were held during data analysis to explore patients' underlying reasoning, to discuss deviant cases and to reach agreement on recurrent themes based on the pattern and relationship between the categories.
SC helped conceive the study, assisted in developing the survey, assisted with day-to-day troubleshooting during the data collection phase and contributed to the preparation of this manuscript.
Field visits probably would better have been conducted earlier during the data collection phase, although, since the problems arose with rural data collection, and most interviewers completed urban data collection first, this might have been falsely reassuring.
In addition, the information discussed during the data collection phase might be emotive or upsetting to participants and/or family members.
