1 · What the graph read from it

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.

Abstract

objectiveType 2 diabetes mellitus is characterized by insulin resistance and defects in insulin secretion from pancreatic beta-cells, which have been studied by using euglycemic/hyperinsulinemic clamps. However, it is difficult to study insulin resistance and beta-cell failure by these techniques in humans. Therefore, the aim of this study was to evaluate the effect of three different antidiabetic therapeutic regimens on insulin resistance and beta-cell activity by using a mathematical model, Homeostasis Model Assessment for insulin resistance (HOMA(IR)) and beta-cell function (HOMA(beta-cell)). RESEARCH DESIGN AND

methodsSeventy type 2 diabetic patients were randomly assigned to one of three therapeutic regimens: (A) metformin + American Diabetic Association (ADA)-recommended diet + physical activity; (B) metformin + low-dose glimepiride + ADA diet + physical activity; or (C) ADA diet + physical activity (no drugs). Blood samples were obtained before and after the treatment to determine serum levels of fasting and post-prandial blood glucose, fasting insulin, and glycosylated hemoglobin (HbA1c), and HOMA(IR) and HOMA(beta-cell) were calculated.

resultsFasting and post-prandial levels of glucose, HbA1c, and fasting insulin and calculated HOMA(IR) and HOMA(beta-cell) values before treatment were significantly higher than the respective values after treatment for all groups of patients (P < 0.01). Significant differences were also found when comparing the treatment-induced reduction in fasting blood glucose (51.8%; P < 0.01), post-prandial blood glucose (55.0%; P < 0.05), and HOMA(IR) (65.3%; P < 0.01) in patients of Group B with that in patients receiving other therapeutic options (Groups A and C).

conclusionsMetformin plus low-dose glimepiride (plus ADA diet and physical activity) is a more effective treatment for type 2 diabetes than either metformin plus ADA diet and physical activity or ADA diet and physical activity alone. Determination of HOMA(IR) and HOMA(beta-cell) values is an inexpensive, reliable, less invasive, and less labor-intensive method than other tests to estimate insulin resistance and beta-cell function in patients with type 2 diabetes mellitus.
