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

The rise of multidrug-resistant (MDR) bacterial pathogens presents a critical challenge to global health, highlighting the need for innovative therapeutic strategies beyond conventional antibiotics. Antibody-antibiotic conjugates (AACs) combine the high specificity of monoclonal antibodies with the potent bactericidal activity of antibiotics, offering targeted delivery to extracellular and intracellular bacteria while minimizing off-target toxicity. The present review provides a comprehensive analysis of AAC development, including key components, such as antigen selection, antibody engineering, linker chemistry, antibiotic payload optimization, and bioconjugation strategies. We summarize the mechanistic principles underlying AAC-mediated bacterial clearance, emphasizing targeted payload release, fragment crystallizable region of the antibody (Fc)-mediated immune engagement, and intracellular delivery. The temporal evolution of AACs is examined, highlighting milestones from early proof-of-concept studies to modern site-specific, humanized constructs and emerging bispecific or dual-payload designs. Furthermore, clinical development is discussed, focusing on pharmacokinetics, pharmacodynamics, safety, efficacy, and regulatory considerations, for example, intracellular infections and biofilm-associated infectious agents. Current challenges, including antigen heterogeneity, immunogenicity, linker-payload optimization, and manufacturing scalability, are critically analyzed, alongside strategies for next-generation AACs. Collectively, AACs represent a transformative platform for precision-targeted antimicrobial therapy, bridging gaps left by conventional antibiotics and offering a promising approach to combating MDR bacterial infections and associated clinical complications.
