Endovascular cooling and endothelial activation in hemorrhagic stroke patients.
Trial report in Neurocritical care, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundLittle is known about endothelial activation under the influence of endovascular temperature management. This analysis was designed to measure the endothelial markers Angiopoietin-1 (Ang-1) and -2 (Ang-2) in endovascularly based prophylactic normothermia versus conventional temperature management.
methodsIn this randomized controlled trial patients with spontaneous subarachnoid or spontaneous intracerebral hemorrhage were prospectively enrolled and randomized in two treatment arms: (a) prophylactic normothermia group with target core temperature 36.5°C using endovascular cooling, (b) active control group with conventional stepwise predefined fever management using antipyretic medication and surface cooling. Blood samples were obtained on days 1, 4, and 7. In a substudy Ang-1 and -2 were measured in 63 patients for whom samples on consecutive days were available.
resultsThe median total fever burden during the course of treatment was 0.0°C and 5.9°C h in the endovascular and the conventional group, respectively (P < 0.0001). Angiopoietin serum levels did not yield a statistical difference when comparing the two treatment arms. Ang-1 was significantly lowered, whereas Ang-2 levels were significantly elevated on day 4 compared to baseline levels irrespective of group allocation (P < 0.0001). The application of non-steroidal anti-inflammatory drugs (NSAIDs) was associated with significantly increased Ang-1 (P < 0.05) and lower Ang-2 levels on day 7 (P < 0.05).
conclusionsEndovascular long-term temperature management did not alter Ang-1 and -2 levels compared to the control group indicating that the endovascular cooling technique itself does not lead to additional endothelial impairment. However, application of NSAIDs led to lower Ang-2 serum concentrations in the endovascular group.
