Although we carefully selected eligible study sites across urban, peri-urban and rural areas, and carried out a number of visits prior to the start of data collection, data were collected in urbanised districts in Zambia and may not be representative of more isolated areas, in which the access to ART is limited further by the inaccessibility and scarcity of health care facilities.
An initial observation occurred at the start of data collection after which subsequent interactions were sampled to observe, with the aim of collecting pertinent data but also related to what was achievable by one researcher within the time frame of the study.
The start of data collection is triggered at the same point for each experimental run.
The phase offset, φR, is the angular difference between the start of data collection and the alignment of the crystal axis of the top cavity with geographical East.
All exclusion criteria were determined before the start of data collection.
Ethical approval to perform the study was granted from the Institutional Review Boards of McGill University and the Massachusetts General Hospital before the start of data collection.
Shown are heart rate (in beats per minute) from the start of data collection until completion for (i) neutral speech entry only, (ii) cognitive task stress with speech entry using race car simulator, and (iii) physical task stress with speech entry using stair stepper.
At the start of data collection in October 2007, the Sonso study community of chimpanzees consisted of 81 named individuals.
At least 30 minutes prior to the start of data collection, the concentration of K+ in the aCSF was raised from 3 to 9 mM to ensure the production of long-term, stable inspiratory-related rhythm.
The first meeting was conducted before start of data collection.
Data analysis was inductive, continuous and began from the start of data collection.
