A qualitative data analysis using the immersion/crystallization technique [ 8, 9] was used to examine the interview transcripts.
As a first step, two researchers (DB and SB) independently examined the interview transcripts to identify issues and concepts apparent in the data.
Thematic analysis was used to examine the interview transcripts in relation to factors that contribute to positive, negative or neutral trajectories.
The validity of the themes and meanings in this study are strengthened as both researchers independently examined the interview data for themes and meanings for each question and then corroborated the evidence for the presented themes and meanings.
By examining the clinician interviews in detail we identified three key system factors for specific networks (table 1 extracts are numbered and referred to in the text).
This involved examining the transcribed interviews to identify key issues and then coding and categorising text expressing these recurrent issues to form explanatory themes.
They also performed a thematic analysis of the interviews, examining the major themes and ideas that arose in each interview [28], including an analysis of the differences between the answers of interviewees working at the country level and those working at the global level.
The interviewer examined the 12 interviews to determine whether content saturation had been achieved.
In addition, the government investigators, by examining the vehicles and interviewing the drivers in addition to downloading data, found one instance of the accelerator pedal's becoming stuck under the floor mat, and no cases of a sticky pedal.
