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

Radiotherapy plays a crucial role in antitumor immunity in glioblastoma, yet its efficacy is often limited, resulting in tumor recurrence. Here, we engineer a macrophage membrane-camouflaged Bacillus Calmette-Guérin (BCG) via bioorthogonal chemistry to enhance radiotherapy against glioblastoma. This engineered BCG penetrates the blood-brain barrier, targets tumors, and alleviates hypoxia through intrinsic catalase activity, exerting antitumor effects in both murine orthotopic glioblastoma and humanized mouse models. Notably, it also initiates trained immunity in tumor-associated macrophages. Depletion and adoptive transfer of tumor-associated macrophages demonstrate that trained immunity promotes inflammatory cytokine production, reactive oxygen species release, phagocytosis and the recruitment of CD8
