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

Infections caused by methicillin-resistant staphylococci (MRS), such as methicillin-resistant Staphylococcus aureus (MRSA), pose significant challenges to public health. The early detection of MRS infections and monitoring of antibiotic resistance profiles are critical for patient management and infection control strategies. Extracellular vesicles (EVs) have emerged as promising biomarkers in infectious disease. By combining single-particle nano-flow cytometry and immunoelectron microscopy (immuno-TEM), we discovered that PBP2a is present on the surface of EVs extracted from MRS. However, whether PBP2a can serve as an EVs-associated protein marker for diagnosing bacterial infections remains unexplored. Using MRSA as a model strain, mouse models of localized and systemic infections were established, alongside a clinical cohort study, to investigate the dynamics of PBP2a-positive (PBP2a
