  1. 1 Conscript was moved to a different brigade.
  2. 2 P-value for difference between the companies.
  3. 3 P-value was examined by using a Kruskall-Wallis test for median difference.
  4. 4 P-value was examined by using χ2 statistics for difference.
  5. 5 MFI is the sum of individual muscle fitness test results comprising push-up, sit-up, pull-up, standing long jump and back lift tests (Excellent = 13-15 points, Good = 9-12 points, Fair good = 5-8 points, Poor = 0-4 points).
  6. 6 CPFI = (12 minute running test result (metres) + 100 × MFI)/200, (Excellent [CPFI ≥ 21.00], Good [17.00 ≤ CPFI < 21.00], Fair good [13.00 ≤ CPFI < 17.00], Poor [CPFI < 13.00]).
  7. 7 Graduated or studies in higher education institution.
  8. 8 Sweating exercise at least three times per week during the last month before military entry.
  9. 9 Compared to age-mates.
  10. 10 Symptoms lasting more than seven days in at least one anatomical region during the last month before entering the military.
