This study is based on one data set with one type of simulated outbreak (approximately lognormal with varying numbers of days), one type of sequential test (Page's) and one nominal false alarm rate (one false alarm per year).
Although it is difficult to draw conclusions based on one data set for injection and one data set for pour-on, some observations are worthwhile to mention.
Additional engagement activities included interdepartmental visits, facility site tours, one-on-one interviews, electronic data sharing, and collaboration on written and oral presentations.
But it was a fascinating experiment, and I quickly realized that thanks to the new possibilities opened up by some clever apps,one-on-one data communication is gradually becoming more interesting.
The following approaches were used to improve the validity of the data: 1) a data dictionary and operations manual were created with explicit instructions for completion of the data collection forms; 2) the data collection protocol was discussed during conference calls along with frequent one-on-one communication; and 3) anomalous data in the data reports were routinely searched for and corrected.
Most studies (65) used one-on-one interviews to collect data, with as few as six individuals interviewed in a study (Larsson et al. 2006) and as many as 93 (Messias and Lacy 2007).
"That time, I showed Tony the data one-on-one," Villeda told me.
This analysis identified a variety of qualitative techniques reported, with most studies relying on one-on-one interviews for their qualitative data.
Triangulation of one-on-one and focus group interview data helped enhance the credibility of the findings by enabling cross verification from these two forms of interview.
Participants will attend 3 screening and dietary education visits, and 7 monthly one-on-one dietary counseling and clinical data measurement visits in addition to 5 group visits in the intervention arms.
Also, the use of one-on-one telephone interviews to collect data may reduce some forms of response bias as participants are less affected by cues from facial expressions or perceived social desirability from the researcher (e.g. in one-on-one interviews) or other participants (e.g. in a focus group setting) [ 58, 59].
