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

Autophagy, a vital catabolic process, plays a crucial role in maintaining pancreatic β cell function and is disrupted in established type 1 diabetes. However, it is unclear when and how this critical cell process becomes defective during type 1 diabetes pathogenesis. To study the nature of autophagy dysfunction in the context of autoimmune diabetes, we used real-time intravital microscopy to study autophagic flux in vivo. We generated an AAV8-packaged mCherry-eGFP-LC3B biosensor driven by the insulin promoter for β cell-selective expression. For real-time autophagic flux evaluation, fluorescent signals from eGFP and mCherry fluorophores were correlated in space and time to follow the process of autophagosome-lysosome fusion. We observed autophagic flux defects in the β cells of the nonobese diabetic (NOD) mouse model of type 1 diabetes before hyperglycemia onset at both baseline and in response to interferon-α. These defects were still present, although less apparent, in immunodeficient NOD/
