1 · What the graph read from it

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.

2 · The registry

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

Feeding is a critical behavior that animals depend on for survival, and pathological alterations in food intake underlie disorders such as obesity and anorexia nervosa. To understand these disorders and their development in animal models, researchers must quantify food intake. Although conceptually straightforward, it remains a challenge to obtain accurate records of food intake in rodents. Several approaches have been used to accomplish this, each with benefits and drawbacks. In this article, we survey the four most common methods for measuring food intake in rodents: manual weighing of food, automated weighing scales, pellet dispensers, and video-based analyses. We highlight each method's benefits and drawbacks for use in feeding research, focusing on accuracy, potential sources of errors, affordability, and practical concerns relating to their use. Finally, we discuss the outlook for feeding devices and unmet challenges for measuring food intake in laboratory rodents.
