1. The cohort size (n) per PGY in italic subheading contributes to the calculations of the overall mean duration contributed by each graduate in each PGY (i.e., the final row of the table)
2. aOf N = 468, there were 348 graduates who did not contribute any tour (of at least 1 year consecutively) of rural service. The remaining 120 graduates had at least 1 tour, 11 with at least 2 tours, 4 with at least 3 tours, and 1 with 4 tours. Worded differently, 109 graduates had only 1 tour, 7 with 2 tours, 3 with 3 tours, and 1 with 4 tours
3. bA ‘tour’ of rural service here is defined as of at least 1 full calendar year (52 weeks) continuous duration
4. cSummary tour statistics are calculated among graduates incurring the concerned tours of service only. For example, Tour 1’s duration is calculated based on n = 120 graduates who contributed at least 1 tour of rural service (of at least 1 full calendar year long), and excludes n = 348 graduates with zero tour in rural work
