Influence of Isoflurane Anesthesia on Plasma Thyroxine Concentrations in Black-tailed Prairie Dogs (

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
Anesthesia can affect measured thyroxine (total T4) concentrations in humans and animals, but its effect in black-tailed prairie dogs (Cynomys ludovicianus) has not yet been studied. We used isoflurane to anesthetize 12 prairie dogs for 60 min. Blood samples were obtained from each animal immediately after anesthesia induction and at 30 and 60 min and used for analysis of plasma T4 concentration. The plasma T4 concentration (mean ± 1 SD) was significantly decreased from baseline (3.49 ± 0.52 μg/dL) at both 30 min (3.24 ± 0.52 μg/dL) and 60 min (3.27 ± 0.65 μg/dL) after induction. Compared with baseline, some of the T4 trends were inconsistent between animals, and individual variability in response was responsible for 86% of the overall variability. Regardless of the observed change under isoflurane anesthesia, all measurements in all prairie dogs and at all time points (2.4 to 4.4 μg/dL) were within the reported normal plasma T4 reference range for this species. In conclusion, isoflurane anesthesia appears to cause a significant but inconsistent reduction in plasma T4 concentrations in black-tailed prairie dogs, but because values remain within normal basal levels, the clinical importance of this effect is likely minimal.
