Relationship between glucose response curve shape during the oral glucose tolerance test and macrovascular complications in type 2 diabetes mellitus.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionThis study evaluated the predictive value of glucose response curve shape during the oral glucose tolerance test (OGTT) for macrovascular complications in patients with type 2 diabetes mellitus (T2DM). RESEARCH DESIGN AND
methodsA retrospective observational analysis was conducted involving 75 subjects with normal glucose tolerance (NGT) and 496 patients with T2DM, all of whom underwent a 3-hour OGTT, along with insulin and C-peptide release tests. Multivariate linear regression models assessed the cross-sectional associations between glucose response curve shapes and common carotid artery (CCA) diameter and intima-media thickness (IMT) in T2DM patients. Risk factors for carotid atherosclerosis analyzed using multivariate logistic regression.
resultsAmong patients with type 2 diabetes who underwent OGTT, the group with monophasic curves (n = 282) showed higher blood glucose levels, increased insulin resistance, and poorer pancreatic β-cell function compared to the multiphasic curve group (n = 214). Larger CCA diameters were independently associated with monophasic curves compared to multiphasic curves (regression coefficient: 0.134 [0.016, 0.252], P = 0.026). Increased IMT was independently associated with monophasic curves compared to multiphase curves (regression coefficient: 0.038 [0.001, 0.075], P = 0.045). Independent risk factors for carotid atherosclerosis in T2DM patients included monophasic curve (odds ratio [OR] 2.014, 95% confidence interval [CI] 1.300-3.121, P = 0.002), age (OR 1.040, 95% CI 1.020-1.059, P < 0.001), male sex (OR 2.107, 95% CI 1.364-3.256, P = 0.001), and duration of diabetes (OR 1.043, 95% CI 1.009-1.078, P = 0.012).
conclusionThe shape of the glucose response curve during OGTT was significantly linked to the risk of macrovascular complications in T2DM patients. Those with monophasic glucose curves were at an elevated risk of developing such complications.
