Ocular temperature measured by infrared thermography in dogs varies with biological and environmental factors.

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
Non-contact temperature assessment is highly valuable for screening animal populations, but its performance can be influenced by various external and biological variables. This study aimed to quantify the association between eye temperature (ET) and rectal temperature (RT) in dogs, and to identify physiological and environmental factors associated with these readings. Field study: ET was obtained with a thermal camera up to 3 times per visit (~10-min intervals), followed by RT measurement. Eye temperature was defined as the highest temperature recorded from either eye. A linear mixed-effects model evaluated ET in relation to capture time (1-3), RT, age, sex, body size, coat length, ambient temperature, and relative humidity. Device temporal stability assessment: To account for potential camera drift observed in our previous research, temperature at a fixed target inside an insulated box was recorded every 5 min for 1 h and analyzed with repeated-measures mixed model regression. Results. We analyzed 129 observations from 78 dogs. In the final ET model, both RT (
