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

backgroundType 2 diabetes mellitus (T2DM) is associated with an increased risk of atherosclerotic vascular disease, but it is unknown whether the other way around is true too. C57BL/6 (B6) and BALB/cJ (BALB) are two mouse strains that differ markedly in their susceptibility to atherosclerosis. In this study we investigated the development of diet-induced T2DM in these two strains. METHODS AND

resultsWhen deficient in apolipoprotein E (apoE(-/-)) and fed a Western diet for 12 weeks, atherosclerosis-susceptible B6 mice developed significant hyperglycemia. In contrast, atherosclerosis-resistant BALB apoE(-/-) mice had much lower plasma glucose levels than B6.apoE(-/-) mice on either chow or Western diet and during an intraperitoneal glucose tolerance test. In response to glucose BALB.apoE(-/-) mice displayed both the first and second phases of insulin secretion but the second phase of insulin secretion was absent in B6.apoE(-/-) mice. In response to insulin B6.apoE(-/-) mice showed a deeper and longer-lasting fall in blood glucose levels while BALB.apoE(-/-) mice showed little reduction in glucose levels. Pancreatic islet area of BALB.apoE(-/-) mice on light microscopy nearly doubled the area of B6.apoE(-/-) mice. Most circulating proinflammatory cytokines were lower in BALB.apoE(-/-) than in B6.apoE(-/-) mice on the Western diet, as determined by protein arrays. Increased macrophage infiltration in islets was observed in B6.apoE(-/-) mice by immunostaining for Mac2 and also by flow cytometry.

conclusionThis study demonstrates that defects in insulin secretion rather than defects in insulin resistance explain the marketed difference in susceptibility to T2DM in the B6.apoE(-/-) and BALB.apoE(-/-) mouse model. A smaller islet mass and more prominent islet inflammation may explain the vulnerability of B6.apoE(-/-) mice to diet-induced diabetes.
