A novel needle-free method of lidocaine administration during standing castration of Holstein bulls.

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
The American Veterinary Medical Association recognizes castration to be important for both human and animal safety. Lidocaine delivered through-the-needle has been shown to be effective at reducing cortisol response to castration, but this method has drawbacks for both animals and caretakers. As such, a study was conducted to examine the potential benefits of lidocaine delivery using a pneumatic needle-free device immediately before standing bovine castration. Twelve Holstein bulls weighing 400.7 ± 39.5 kg (mean ± standard deviation) were enrolled. Bulls were allocated to receive a local anesthetic block of 2% lidocaine for surgical castration by traditional needle injection or by needle-free injection. Outcomes were collected out to 48 h postcastration. Outcome variables included plasma cortisol concentrations, visual analog scale scores for pain, medial canthus temperatures as measured using infrared thermography, pressure mat changes, and chute defense scores. A time effect was observed for cortisol, visual analog scale scores, infrared thermography temperatures, and some pressure mat outcomes. No statistically significant differences between lidocaine delivery methods were observed, but further research is needed to build upon this small dataset.
