A tale of two ligands: angiopoietins, the endothelium, and outcomes.
Article in Critical care (London, England), 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
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
Angiopoietins signal via the Tie-2 receptor and are essential molecules for vasculogenesis during development and in the adult state play roles in vascular stability as well as inflammation and appear to be involved in the dysregulation of the endothelium in illness. Angiopoietin-1 (Ang-1) and angiopoietin-2 (Ang-2) are, respectively, agonists and competitive partial agonists, which have been found to undergo alterations in individuals with sepsis. In sepsis, Ang-2 levels are elevated and Ang-1 is decreased. In the previous issue of Critical Care, Fiusa and colleagues measure circulating Ang-1 and Ang-2 along with other growth factors in humans with febrile neutropenia. The authors found that an increased Ang-2/Ang-1 ratio, or an elevated Ang-2 level, at the time of an initial fever, is associated with subsequent development of septic shock and death. These findings validate that the Ang-2/Ang-1 balance, which is thought to reflect overall signaling via the Tie-2 receptor, is relevant to outcomes in patients with sepsis. Importantly, the specimens were obtained far in advance of the development of septic shock, suggesting that detectable alterations in this pathway may provide early clues regarding outcomes. This study adds to the evidence that angiopoietins are early markers of endothelial dysfunction in sepsis and provide prognostic information regarding outcomes.
