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

Type 2 diabetes (T2D) is a complex metabolic disease characterized by insulin resistance, progressive β-cell dysfunction, and persistent hyperglycemia. While GLP-1 receptor agonists have revolutionized the management of T2D by improving glycemic control and reducing body weight, their insulinotropic effects increase the workload on pancreatic β-cells, which may hasten β-cell decline in certain individuals. Peptide YY (PYY), a gut-derived hormone secreted alongside glucagon-like peptide-1 (GLP-1) from L-cells, presents a unique and complementary therapeutic approach. In contrast to GLP-1, PYY does not directly induce insulin release but confers metabolic advantages by suppressing appetite through Y2 receptor pathways, enhancing insulin sensitivity via peripheral Y1/Y4 receptors, and slowing gastric emptying to minimize postprandial glucose surges. Notably, recent research suggests PYY supports the preservation and restoration of pancreatic islets by improving their structure and function without increasing the secretory demand. PYY levels are substantially increased after bariatric surgery, where it plays a pivotal role in weight-loss-independent improvements in glycemic regulation and islet hormone dynamics. These attributes position PYY as a strong candidate for use in combination with GLP-1 analogs, especially in individuals with advanced β-cell impairment or those who respond inadequately to GLP-1 monotherapy. This review discusses PYY's physiological functions, mechanistic actions, and therapeutic opportunities in T2D, highlighting its potential as a valuable adjunct or alternative in gut-hormone-oriented treatment strategies.
