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

Engineered live biotherapeutic products (eLBPs) represent an emerging class of programmable microbial therapies capable of sensing and responding to host physiology. Advances in microbiome science and synthetic biology have driven the development of engineered bacteria that deliver therapeutic molecules, modulate host metabolism, or detect disease-associated signals. In this review, we summarize recent progress in the development of eLBPs across diverse disease indications, including inflammatory diseases, metabolic disorders, cancer, and infectious diseases. We highlight key factors that drive successful eLBP design, including chassis selection, methods for DNA delivery, approaches for tuning therapeutic expression, and genetic systems for biocontainment. Although early clinical studies demonstrate promising safety profiles, challenges remain in achieving predictable colonization, durable therapeutic activity, and robust biocontainment in vivo. By synthesizing advances across these areas, we propose a framework for the rational design of next-generation eLBPs that can more reliably translate from experimental systems to clinical application.
