In the first phase, pilgrims attending the BHD Medical Clinic were informed about the study and the procedure for taking samples, and were invited to participate if suffering from symptoms of URTI.
Following the intensive phase, participants attended a tapering phase where participants met for a total of eight one-hour visits over three months.
Once the subjects reached criterion, we reversed the association between the cloth colour and the food reward in Phase 2. If the subjects solved the problems in Phase 1 by attending to cloth colour, then in Phase 2 they should have difficulty, especially given prior findings on tamarins demonstrating that reversal learning is difficult.
In the second phase, participants attended a semi-structured focus group.
To mimic a maintenance phase, children attended the program every other week for the next 6 months.
In the bachelor phase students attend training sessions in communication skills, physical examination skills, and clinical reasoning separately from one another.
If the subjects solved Phase 1 by attending to the functionality of the problem (i.e. the physical/causal relationship between the cloth and food), then reversing the colours in Phase 2 should have no effect on the subjects' performances.
Patients attending Phase II CR were significantly younger compared to patients who did not attend CR and thus subsequent analyses were age-adjusted.
Survey instrument was used in phase 1, couples attending the specialized clinic were interviewed together to ensure accuracy of their responses; although, different checklists were completed for husband and wife by the consultant doctor (one of the researchers).
Among those attending phase 2, only persons with valid bone mineral density (BMD) measurement from Tromsø V in 2001/2002 were invited for a Dual X-ray (DXA) BMD measurement of the hip, i.e. a dual femur scan, and altogether 3854 persons attended.
