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

backgroundVascular and inflammatory processes have been reported to be factors in the pathogenesis of diabetic neuropathy. Angiopoietin-1 (Ang1) plays essential roles in regulating vascular growth, development, maturation, permeability, and inflammation.

objectiveThe aim of this study was to investigate the effect of cartilage oligomeric matrix protein (COMP)-Ang1, which is a soluble, stable, potent Ang1 variant, on peripheral nerves in db/db diabetic mice.

methodsThe db/db diabetic mice were randomized into 2 groups based on their weight and glucose level and treated with recombinant adenovirus (Ade), expressing either COMP-Ang1 or the β-galactosidase gene (LacZ) (control), for 8 weeks. Immunohistochemistry was performed using a polyclonal antibody of antiprotein gene product and a secondary antibody. Intraepidermal nerve fiber density (IENFD) was quantified as nerve fiber abundance per unit length of epidermis (IENF/mm). In addition, the total capillary length (TCL) per unit length of epidermis was summed (mm/mm(2)). All slides were coded and the capillary length and the number of nerve fibers were calculated by a blinded observer.

resultsTen diabetic db/db mice (mean [SD] weight, 38.7 [1.95] g) were randomized to receive Ade-COMP-Ang1 or Ade-LacZ. IENFD was significantly greater in the Ade-COMP-Ang1 group compared with the Ade-LacZ group (mean [SD] 8.95 [3.30] vs 3.57 [0.73]/mm; P < 0.05). TCL was also significantly greater in the Ade-COMP-Ang1 group (2.79 [0.99] vs 2.04 [0.58] mm/mm(2); P < 0.05). Compared with baseline, fasting blood glucose concentration after 8 weeks of treatment decreased significantly more in the Ade-COMP-Ang1 group than in the Ade-LacZ group (489 [45] to 361 [81] vs 495 [48] to 521 [70] mg/dL; P < 0.05).

conclusionsThese results suggest that Ade-COMP-Ang1 might have had proliferative effects on peripheral nerve and cutaneous capillaries in this small animal study. Further investigation of the metabolic effect, target site, and related mediator of COMP-Ang1 is needed.
