Main Effects
Postprandial mean glucose levels decreased by 2.5 mg/dL (p=0.001).
24-hour mean glucose levels decreased by 3 mg/dL (p=0.001).
The proportion of participants achieving target PPG (<180 mg/dl) increased by 50% (p=0.001).

Evidence Suggest
- Postprandial mean glucose significantly reduced with interventions.
- 24-hour mean glucose levels were notably lower, especially with acarbose.
- Higher proportion of participants reached target PPG levels with acarbose.
Who this applies to
- Adults diagnosed with type 2 diabetes.
- Individuals seeking dietary and pharmaceutical options for blood sugar management.
Keep in Mind
- Results may not apply to all demographics due to study population.
- Effectiveness may vary based on individual adherence to dietary changes.
- Further research needed to explore long-term outcomes and safety.
Between the Lines
- Limited generalizability due to specific population characteristics.
- Potential confounding factors not fully controlled.
- Short duration of follow-up may not capture long-term effects.
