This population information refers to the materialized supporting studies available for review. Omitted support records remain part of the authoritative support accounting and are available through the audit experience.
View reported population descriptions
These descriptions are reported across the supporting studies; they are not a single synthesized population.
- Adults aged 18-65 years with prediabetes in two sub-urban communities in Seremban, Malaysia
- Adults with non-diabetic hyperglycaemia (NDH/prediabetes) identified via two-stage risk score screening, aged 40-75 y (white European) or 25-75 y (South Asian)
- kg/m2
- FINDRISC >14 and no diagnosed diabetes
- Women with prior gestational diabetes mellitus (GDM) within their first postnatal year. At baseline, 10% had impaired glucose tolerance and 2% had impaired fasting glucose. Mean glucose profiles were near normal.
Limitations
- Evidence uses heterogeneous comparison contexts: baseline_within_group, usual_care.
- 3 supporting studies have high, serious, critical, unclear, or unavailable risk-of-bias information.
- 1 study contains conflicting p-value and significance fields; those significance claims are suppressed.
