Table 2 Behavioural outcomes with adjusted between-group differences and quantitative and qualitative inferencesa

From: Evaluation of sit-stand workstations in an office setting: a randomised controlled trial

  Intervention (n = 23) Control (n = 21) Adjusted change 0 to 4 week (95 % CI)b Adjusted change 0 to 8 week (95 % CI)b Probability (%) the true effect is beneficial / trivial / harmful Qualitative inference (8 week)
(minutes/8-hour workday) Baseline 4 week 8 week Baseline 4 week 8 week
Sitting time 385.9 (57.6) 299.2 (93.4) 322.0 (99.3) 387.0 (41.0) 387.5 (78.0) 402.2 (47.9) −87.6 (−136.8 to −38.3)* −80.2 (−129.0 to −31.4) * 79/21/0 Benefit likely
Standing time 41.1 (35.0) 141.1 (98.0) 115.4 (111.6) 42.5 (26.0) 61.0 (76.2) 43.7 (50.2) 82.2 (36.5 to 127.8)* 72.9 (21.2 to 124.6)* 69/31/0 Benefit possible
Walking time 53.0 (41.2) 39.7 (33.4) 42.6 (42.3) 50.5 (24.2) 31.4 (24.4) 34.0 (29.1) 7.3 (−8.7 to 23.2) 7.1 (−12.1 to 26.3) 38/58/4 Possibly trivial
  1. aBaseline, 4- and 8-week values are unadjusted mean (SD)
  2. bChange scores and 95 % CIs are the differences between groups (relative to control) after adjustment by ANCOVA for the baseline value
  3. *Significant (p <0.05)
