Plain-language summary
A plain-language read of the study’s main message and where it applies.
Study focus
Text message-delivered self-management support improved glycemic control in patients with Type 2 diabetes, particularly in HbA1c levels.
Improving glycemic control is crucial for reducing the risk of diabetes-related complications. Text message support offers a practical, scalable method for enhancing self-management in patients with Type 2 diabetes, potentially leading to better health outcomes and quality of life.
Unclear effectiveness for eGFR and proteinuria outcomes. Limited generalizability due to specific population characteristics. Potential unmeasured confounders affecting results.

HbA1c significantly improved in the intervention group (decrease of -1.2%, p = 0.001).
No significant effect on eGFR from baseline to follow-up (no change, p = 0.11).
Trending interaction effect between intervention and presence of proteinuria at baseline (b = 6.016, p = 0.099).
