  1. 1 adjusted for all variables displayed in the table except education
  2. 2 OR = 12.7 (2.6-61.5), due to small numbers estimates become unreliable
  3. All estimates and 95% CI are based on the pooled data for the one-year outcome conditional to previous physical activity level using the GEE model with an independent correlation structure for the within-subject association. Only observations were included with data for the preceding wave in individuals previously active in sports (nmale participants = 951; nfemale participants = 931) or previously active (nmale participants = 933; nfemale participants = 936)
