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.

2 · The registry

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

Bitter taste-sensing type 2 receptors (TAS2Rs) were first discovered in the oral cavity, but their detection in extra-oral tissues like gastrointestinal tract and kidney leads to modulation of multiple (patho) physiological processes. Krüppel-like factor (KLF6) is a novel regulator of β-cell adaptation to metabolic stress and involved in multiple processes in vascular system. This research aimed to assess the possible metabolic and renal protective effect of TAS2R agonist denatonium benzoate and the antidiabetic drug sitagliptin in diabetic rats. Forty male Sprague Dawley rats were included and divided into two main groups: normal control group and fructose-fed streptozotocin-induced diabetic group. Diabetic group was subdivided into four subgroups untreated: sitagliptin, denatonium, and sitagliptin + denatonium-treated groups. All treated groups showed improvement of glycemic and lipid profiles and UACR with enhancement of renal KLF6 expression and improved histological architecture of diabetic kidney. The combination group showed the best results with most renal corpuscles returning to normal and biochemical values close to normal control. Compared to the diabetic control group, the combination group showed significantly lower fasting blood glucose, HbA1C, UACR, TGs, and LDL-C values (≈3.44, 2.1, 3.5, 1.6, and 1.5-fold reduction, respectively), and significant elevation of serum GLP, HDL-C, and renal KLF6 expression (≈2.1, 2.0, and 3.7-fold increase, respectively). Significant correlations were detected between KLF6 expression and various parameters in all rats of the experiment. This study concluded the promising role of denatonium benzoate and its combination with sitagliptin in the management of diabetes and its renal complications.
