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 (NCT07840846). This is a study registration, not published results. Lead sponsor: The First Affiliated Hospital of China University of Science and Technology (Anhui Provincial). Recruitment status: NOT_YET_RECRUITING. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 138 participants (ESTIMATED). Conditions: Hypertriglyceridemia, Overweight , Obesity. Interventions: DIETARY_SUPPLEMENT: Standardized Large Yellow Tea Extract; DIETARY_SUPPLEMENT: Placebo. Primary outcome measures: Change From Baseline in Fasting Triglyceride Level at Week 12 , Baseline and Week 12. Brief summary: This multicenter, prospective, randomized, blinded, parallel-group controlled trial will evaluate the effects of standardized large yellow tea extract on glucose and lipid metabolism in overweight adults with elevated triglyceride levels. Approximately 138 participants aged 18 to 60 years will be enrolled at three study centers in China and randomly assigned in a 1:2 ratio to a placebo control group or a standardized large yellow tea extract group. Participants will receive the assigned intervention for 12 weeks, together with standardized lifestyle guidance. The primary objective is to compare the change in fasting triglyceride levels from baseline to week 12 between the two groups. Secondary objectives include evaluating changes in other lipid parameters, glucose metabolism, body weight, body mass index, waist circumference, blood pressure, and safety and tolerability. Exploratory analyses will assess plasma and/or urine metabolomic profiles and potential biomarkers related to response to the tea intervention. Participants will also be followed through week 24 for longer-term safety assessment and changes in glucose and lipid metabolism.
