1. Research Methods
1-1. Inclusion criteria
All published and pre-published randomized controlled trials (RCTs), including individual RCTs, cluster RCTs, cross over RCTs.
All languages and countries.
1-2. Exclusion criteria
Non-RCTs
2. Search Methods
2-1. Electronic search (the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via Ovid, EMBASE via ProQuest)
2-2 Other resources (the World Health Organization International Clinical Trials Platform Search Portal (ICTRP), ClinicalTrials.gov)
3. Bias risk
Two reviewers will conduct the study independently using the Risk of Bias 2 tool. Disagreements between the two reviewers will be discussed and resolved by the two of them. Discuss with a third reviewer, if necessary.
4. Evaluation of treatment effects
Meta-analysis of standardized mean difference (SMD) and 95% CIs for the following continuous variables: HbA1c concentrations, Physical component summary score, Mental component summary score, Plasma glucose, Plasma insulin, Plasma incretin.
Adverse events will be summarized according to the definitions of each study.
5. Subgroup analysis and the search for heterogeneity
(For P) Stratified analysis by gender.
(For I) Limit the type of staple food to rice only. Limit non-staple foods to vegetables, fatty foods, or protein only.
6. Sensitivity analysis
6-1. Exclusion of studies using imputed statistics.
6-2. Missing participants: Verify the robustness of the results by seeking informative missingness odds ratios.
7. Summary of findings Table
SOF tables will be created for the following outcomes.
Primary outcomes
1. HbA1c concentrations (NGSP)
2. Physical component summary score (SF36, SF12, SF8)
3. Mental component summary score (SF36, SF12, SF8)
Secondary outcomes
4. Plasma glucose after 120 min of meal
5. Plasma insulin after 120 min of meal
6. Plasma incretin (GLP-1, GIP) after 120 min of meal
7. All adverse events
