Table 2 Univariate Meta-regression Analysis at First Time Point (≤4 months) to Investigate Effect-Modifiers

From: The effects of step-count monitoring interventions on physical activity: systematic review and meta-analysis of community-based randomised controlled trials in adults

Effect Modifier Factor Univariate Mean Difference [95% CI] Univariate Difference between Effect Modifier Groups
Mean [95% CI]
Mutually Adjusted Difference between Effect Modifier Groups
Mean [95% CI]
Study Outcome Type Change-on-Change Studies 1215 [737, 1692]   
End-point Only Studies 1831 [1307, 2355] 616 [−92, 1324] 257 [−417, 931]
Type of Monitor Pedometer 1716 [1303, 2129]   
Other Step-count Monitoring Interventions 789 [178, 1401] −927 [−1633, −190] −834 [−1542, −126]
Intensity of Interventiona Intervention without PA individual or group counselling 2067 [1520, 2614]   
Intervention with PA individual or group counselling or other incentives (e.g. cash or charity) 1136 [711, 1561] −931 [−1623, −239] −812 [−1503, −122]
  1. a4 studies had missing grade
  2. Above all based on REML models. Using mm2 model has little impact on meta-regression
