Abstract
This article details a correction to: Bamgboye M, Adeyemi D, Agaba E, Yilme S, Adebamowo CA, Adebamowo, SN. A Randomized Controlled Trial to Examine the Relationship Between Peer Mentoring for Physical Activity and Cardiometabolic Health. Global Heart. 2023; 18(1): 53. DOI: https://doi.org/10.5334/gh.1268.
Keywords: peer mentoring, physical activity, cardiometabolic health, randomized controlled trial
Correction
Content of correction Some errors were identified in the original publication [1], 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.

Difference = difference between means. Min = minutes; hr = hours. P-value* = P-value comparing the mean values within each group, with a paired t-test. P-value# = P-value comparing the difference in mean values between the groups, with a t-test.
– 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.

LDL = low-density lipoproteins. HDL = high-density lipoproteins. Chol = cholesterol. Difference = difference between means. P-value* = P-value comparing the mean values within each group, with a paired t-test. P-value# = P-value comparing the difference in mean values between the groups, with a t-test.
– Figure 3 was revised to clarify the direction of change for each parameter.
Figure 3.
Change in cardiometabolic parameters by group.
a. change in low-density lipoproteins (LDL). b. change in triglycerides. c. change in cholesterol. d. change in high-density lipoproteins (HDL).
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.
