Correction
Content of correction Some errors were identified in the original publication [], primarily stemming from rounding inaccuracies or failure to update tables/figures after implementing changes.
- – In Table 3, discrepancies were found where the Weekly METS was expressed in minutes, but the difference was expressed in hours. An updated Table 3 (provided below) presents all results consistently in minutes and hours; one corrected value is highlighted in bold.

- – Table 5 contained two inaccuracies; specifically, the difference in the control group was –0.004 for waist-to-hip ratio (not –0.0009), and –0.2 for visceral fat (not +0.2). In the updated Table 5 (provided below) these corrected values are highlighted in bold.

- – Figure 3 was revised to clarify the direction of change for each parameter.
We emphasize that due to the culture at the enrolment site, the observations are not dependent within the same office space.
These corrections do not change the overall results or conclusions.
