Angiotensin receptors as sensitive markers of acute bronchiole injury after lung transplantation.
Article in Lung, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundAlthough lung transplantation is the only means of survival for patients with end-stage pulmonary disease, outcomes from this intervention are inferior to other solid organ transplants. The reason for the poor outcomes may be linked to an early reaction, such as primary graft dysfunction, and associated with marked inflammatory response, bronchiole injury, and later fibrotic responses. Mediators regulating these effects include angiotensin II and matrix metalloproteinases (MMPs).
methodsWe investigated changes to these mediators over the course of cardiopulmonary bypass (CPB) and up to 72 h after lung transplantation, using immunohistochemistry, Western blot, and ELISA techniques.
resultsWe found 4- and 16-fold increases in plasma angiotensin II and MMP-9, respectively, from pre-CPB to post-CPB. MMP-9 levels remained elevated 1 h after transplantation. MMP-2 levels were elevated 6-24 h after lung transplantation. Type 2 angiotensin II receptor (ATR2) expression was 3.5-fold higher in bronchoalveolar cells 1-6 h after transplantation than in controls.
conclusionsThe study suggests that the combination of cardiopulmonary bypass and lung transplantation is associated with early changes in the angiotensin II receptor system and in MMPs, and that altered expression of these mediators may be a useful marker to examine pathological changes that occur in lungs during transplant surgery.
