Abstract

We have discovered that the figures 4, 5 and 6 have been mixed up leading to some misunderstanding between the narrative text and the figures. The changes made are as below: On page 13, the figure 4 was renumbered as figure 5. On page 14, figure 5 was renumbered as figure 6 and figure 6 was renumbered as figure 4. The revised text is as below: 3.3.2.1. Effect of the WAT-based interventions on step counts (comparison with a passive control) Details of the pooled effect of WAT-based interventions on step counts (steps/day) are summarized in Fig. 4. In comparison with the control groups (n = 207), there was a significant positive effect on step count, and the standard mean difference was 1.27 (95 % CI [0.51, 2.04], overall effect Z = 3.26 at p = 0.001). Significant heterogeneity was found (I2 = 82 %, p = 0.0008), and the overall result indicated a significant favorable effect on increasing step count. [Figure presented] Figure 4: Comparison of the effect of the WAT-based interventions and the passive control group on step count. 3.3.2.2. Effect of the WAT-based interventions on MVPA (comparison with a passive control) Details of the pooled effect of WAT-based interventions on MVPA (minutes/day) are summarized in Fig. 5. In comparison with the control groups (n = 83), there was a significant positive effect on MVPA, the standard mean difference was 1.23 (95 % CI [0.75, 1.70], and the overall effect Z = 5.04 at p < 0.00001). A non-significant heterogeneity was found (I2 = 0%, p = 0.67), and the overall result indicated a significant favorable effect on increasing MVPA. [Figure presented] Figure 5: Comparison of the effect of the WAT-based interventions and the passive control group on MVPA. 3.3.2.3. Effect of the WAT-based intervention on step counts (comparison with an active control) Details of the pooled effect of the WAT-based interventions on step count (steps/day) are summarized in Fig. 6. In comparison with the active control groups (n = 201), there was a non-significant effect on step count and the standard mean difference was 0.22 (95 % CI [-0.62, 1.06], overall effect Z = 0.51 at p = 0.61). Significant heterogeneity was found (I2 = 88 %, p < 0.001), and the overall result indicated a non-significant favorable effect on increasing step count.
