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

AIMS/

introductionDerangements often observed with type 2 diabetes are associated with disturbances in renin-angiotensin-aldosterone system (RAAS) activity. A positive correlation between local RAAS activity and the complications observed in type 2 diabetes has been noted. However, the detrimental ramifications due to moderate hyperglycemia noted in prediabetes, and the affected organ system and mechanistic pathways are not elucidated. Hence, this study investigated the effects of diet-induced prediabetes on RAAS in various organs. MATERIALS AND

methodsMale Sprague-Dawley rats were separated into two groups: (i) non-prediabetes through exposure to standard rat chow group; and (ii) diet-induced prediabetes group by exposure to a high-fat high-carbohydrate diet for 32 weeks. RAAS activity in the skeletal muscle, adipose tissue, liver, pancreas and heart was determined through the analysis of RAAS components, such as renin, angiotensinogen, angiotensin-converting enzyme and angiotensin II type 1 receptor through polymerase chain reaction, as well as the quantification of angiotensin II and aldosterone concentration. Furthermore, nicotinamide adenine dinucleotide phosphate oxidase, superoxide dismutase and glutathione peroxidase 1 concentrations were determined in the skeletal muscle, pancreas and heart, in addition to the hepatic triglycerides.

resultsThe RAAS components were elevated in the diet-induced prediabetes group when compared with the non-prediabetes group. This was further accompanied by increased nicotinamide adenine dinucleotide phosphate oxidase and reduced superoxide dismutase and glutathione peroxidase 1 concentrations in the selected organs, in addition to the elevated hepatic triglycerides concentration in the diet-induced prediabetes by comparison to non-prediabetes group.

conclusionsDue to these observed changes, we suggest that local RAAS activity in the prediabetes state in selected organs elicits the derangements noted in type 2 diabetes.
