Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT04225507). This is a study registration, not published results. Lead sponsor: University of Chicago. Recruitment status: COMPLETED. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 182 participants (ACTUAL). Conditions: Sleep Apnea, PreDiabetes, Overweight or Obesity. Interventions: BEHAVIORAL: Diet and exercise coaching; OTHER: CPAP Treatment. Primary outcome measures: Change from baseline 2-hour glucose levels at 6 months , Baseline and at 6 months. Brief summary: Despite the efficacy of intensive lifestyle interventions in prediabetes, the incidence of diabetes is rising, and thus there is a critical need for additional strategies to prevent diabetes and to reduce its cardiovascular complications in this high-risk population. Sleep apnea is a highly common condition in prediabetes, but it has been mostly ignored and undertreated in current practice. The proposed study will be the first to assess whether adding CPAP (continuous positive air pressure) treatment to a lifestyle intervention improves cardiometabolic outcomes beyond that achieved with lifestyle alone (i.e. current standard of care) in high-risk individuals with prediabetes.
