  1. Results are regression coefficients (95% CI) from meta-analysis, representing the difference in the outcome variable when increasing that type of activity by 1 h/day while decreasing PST by the same duration and holding other activity components constant. Differences in outcome variables when modelling 30 min/day substitutions instead of 1 h/day substitutions (holding other activity components constant) equate to 50% of the estimates presented above. Statistically significant (P < 0.05) estimates are indicated in bold. Sex-specific associations are provided when a significant interaction with sex was found in Table 3
  2. Models omitted the PST variable under study and incorporated the complementary non-prolonged ST variable of interest, LIPA and MVPA, and are adjusted for wear time (h/day), sex (in total group) and age
  3. Abbrevations: PST prolonged sedentary time, non-PST non-prolonged sedentary time, LIPA light-intensity physical activity, MVPA moderate-to-vigorous physical activity, CCMR clustered cardio-metabolic risk score including waist circumference, CCMRno adip clustered cardio-metabolic risk score excluding waist circumference
  4. N included by outcome: see Table 3
