Effects of Long-term Anesthesia, Blood Sampling, Transportation, and Infection Status on Hearts and Brains in Pigs Inoculated with

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
Laboratory animals are widely used in imaging studies, including infection, heart, and brain research. Compared with rodents, pigs are especially useful because of their large organ sizes, ability to tolerate long-term anesthesia, and substantial blood volume, which allows repeated blood sampling. These factors are particularly important in positron emission tomography studies of potential new radioactive tracers, because the scans often are prolonged; in addition, kinetic studies involving repeated blood sampling may be performed to establish the optimal scan time. However, protracted studies may affect the cardiovascular system, brain, and other organs. This raises the question of how to monitor and counteract the effects of longterm anesthesia in pigs in a typical experimental setting yet prevent introducing bias into the experiment. To address this question, we investigated the effects of long-term anesthesia (maximum, 18 h), repeated blood sampling (maximum of 20 mL blood per kilogram body weight), and road transportation (as long as 1.5 h between 2 imaging centers) on key variables of lung, heart, and brain function in the context of a well-established pig model of
