Methods
- Electronic data bases searched were PubMed/Medline, ProQuest, PsycINFO, IndMED, CENTRAL, Cochrane library, CamQuest and CamBase till December 17, 2014.
- Eligible outcomes were fasting blood sugar (FBS), post prandial blood sugar (PPBS) and glycosylated haemoglobin (HBA1C).
- Randomized controlled trials and controlled trials were eligible. Studies focussing only on relaxation or meditation or multimodal intervention were not included.
- A total of 17 RCTs were included for review.
- Data from research articles on patients, methods, interventions- control and results were extracted.
- Mean and standard deviations were utilized for calculating standardized mean difference with 95% confidence interval.
- Heterogeneity was assessed with the help of I2 statistics.
- χ2 was used to rule out the effects of heterogeneity due to chance alone.
Results
- Beneficial effects of yoga as an add-on intervention to standard treatment in comparison to standard treatment were observed for FBS [Standardized Mean Difference (SMD) -1.40, 95%CI -1.90 to -0.90, p<0.00001]; PPBS [SMD -0.91, 95%CI -1.34 to -0.48, p<0.0001] as well as HBA1C [SMD -0.64, 95%CI -0.97 to -0.30, p<0.0002].
- But risk of bias was overall high for included studies.
