What is a Normal Glucose Value?
Bibliographic record
Abstract
OBJECTIVE: To evaluate differences in indexes of plasma glucose/insulin homeostasis and cardiovascular disease risk factors among subjects with normal fasting glucose (NFG), impaired fasting glucose, or glucose intolerance. Although individuals with fasting plasma glucose (FPG) concentrations > 5.4 mmol/l but < 6.1 mmol/l have been shown to have an increased risk of developing type 2 diabetes over 5 years, little is known about glucose metabolism abnormalities in this population. RESEARCH DESIGN AND METHODS: We compared insulin secretion and insulin sensitivity using several indexes derived from an oral glucose tolerance test (OGTT) in 668 subjects from the Quebec Family Study who had varying degrees of FPG. RESULTS: There was a progressive decline in indexes of beta-cell function and insulin sensitivity when moving from NFG to type 2 diabetes. Compared with subjects with low NFG (FPG < 4.9 mmol/l), subjects with high NFG (FPG 5.3-6.1 mmol/l) were more insulin resistant (P < 0.01), had higher insulin and C-peptide responses during an OGTT (P < 0.05), and had reduced insulin secretion (corrected for insulin resistance). Subjects with high NFG were also characterized by higher plasma triglyceride levels and reduced HDL cholesterol concentrations and by a smaller LDL particle size. All these differences remained significant, even after adjustment for age, sex, BMI, and waist circumference. In addition, subjects with mid NFG (FPG 4.9-5.3 mmol/l) were characterized by impaired insulin secretion, decreased insulin sensitivity, higher triglyceride concentrations, and lower HDL cholesterol concentrations compared with subjects with low NFG. CONCLUSIONS: Independent of age, sex, and adiposity, there are differences in indexes of plasma glucose/insulin homeostasis and in cardiovascular risk factors among subjects with low, mid, and high NFG, suggesting the presence, in the upper normal glucose range, of abnormalities in glucose homeostasis, which may predispose to type 2 diabetes.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
