Triglyceride-Glucose and TGI-BMI Indices Compared With HOMA-IR

Turkey (Türkiye)150 participantsStarted 2024-12-01

Plain-language summary

Insulin resistance plays a key role in the development of type 2 diabetes, metabolic syndrome, and heart disease. The most common way to measure insulin resistance is the HOMA-IR index, but it requires fasting insulin tests, which are not always available in clinical practice. This study aims to assess two simpler and more accessible alternatives: the triglyceride-glucose index (TGI) and its body mass index-adjusted version (TGI-BMI). Data from 150 adult patients were analyzed retrospectively and divided into groups according to their insulin resistance status. Standard laboratory and body measurements were compared between groups, and statistical analyses were used to determine how well TGI and TGI-BMI identify insulin resistance. The results showed that both TGI and TGI-BMI were closely related to insulin resistance and demonstrated high diagnostic accuracy, similar to HOMA-IR. The TGI-BMI index was particularly effective in individuals with obesity. These findings suggest that TGI and TGI-BMI could serve as practical, low-cost alternatives to HOMA-IR for evaluating insulin resistance in clinical and population settings where insulin testing is not routinely available.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Eligible participants were adults aged 18-65 years with complete fasting biochemical and anthropometric data. Only patients who were not receiving antidiabetic medications at the time of evaluation were included. Exclusion Criteria: * Patients were excluded if they had any of the following: * Known endocrine disorders (e.g., thyroid dysfunction, Cushing's syndrome) * Chronic kidney or liver disease * Active infection or systemic inflammatory disease * Ongoing use of medications known to affect glucose or lipid metabolism (e.g., corticosteroids, statins, metformin, or insulin) * Incomplete or missing laboratory data

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
