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

Confined spaces in the human body pose substantial challenges for biomedical procedures. Navigating these ultrasmall environments is essential for precise drug delivery, improving treatment outcomes and reducing adverse effects. Microrobots offer a promising approach to accessing these complex microenvironments. Here, we show a biohybrid microrobot based on picoeukaryotes, engineered as a cargo carrier for active delivery in tight in vivo spaces. The microrobot exhibits strong in vitro motility through narrow two-dimensional and complex three-dimensional networks and, in vivo, achieves outstanding kidney penetration, uniform distribution, and >48-hour retention while resisting flow shear and immune clearance, with excellent biosafety. Their ability to retain functionality and sustain propulsion within the confined and complex kidney vasculatures and interstitial spaces underscore their potential for long-term, active delivery in confined biological environments. The picoeukaryote-based biohybrid microrobot system represents a major advancement in active drug delivery, especially tailored to the challenging microenvironments of the kidney.
