A gastric retentive robotic capsule enables emergency-prepared and responsive oral drug delivery in canine models.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Existing oral drug delivery modalities often fall short in medical emergencies due to the absence of readily deployable, internalized drug storage and delivery mechanisms that combine long-term standby with rapid activation. To address this challenge, we develop and validate a gastric retentive robotic capsule capable of autonomously prepositioning multiple drug doses within the stomach upon oral administration. This system maintains quiescence for extended periods while enabling on-demand, remote-triggered drug release within seconds during emergencies. In a canine (beagle) model, we demonstrate safe gastric residence and functionality for at least 10 weeks, including closed-loop emergency drug delivery modulated by external or onboard biometric sensors for unsupervised symptom detection. At the end of its service life, the capsule can be safely excreted on-demand through the administration of an alkaline solution. These findings establish such a system as a paradigm for emergency-prepared and responsive drug delivery, particularly in vulnerable patient populations.
