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

Cerebral malaria (CM) is a leading cause of death in Plasmodium falciparum infections. In the Plasmodium berghei ANKA (PbA) murine model, CM pathogenesis is associated with low nitric oxide (NO) bioavailability and brain microcirculatory complications, with a marked decrease in cerebral blood flow, vasoconstriction, vascular plugging by adherent cells, and hemorrhages. Using intravital microscopy through a closed cranial window, here we show that NO supplementation in the form of a NO donor (dipropylenetriamine NONOate [DPTA-NO]) prevented vasoconstriction and improved blood flow in pial vessels of PbA-infected mice. Arterioles and venules of smaller diameters (20-35.5 μm) showed better response to treatment than vessels of larger diameters (36-63 μm). Exogenous NO provided protection against brain hemorrhages (mean, 1.4 vs 24.5 hemorrhagic foci per section) and inflammation (mean, 2.5 vs 10.9 adherent leukocytes per 100 μm vessel length) compared with saline treatment. In conclusion, NO protection against CM is associated with improved brain microcirculatory hemodynamics and decreased vascular pathology.
